Log nothing with DDASLLogger in IOS7 on a real device - ios

Using Lumberjack in IOS7 on an ipod5, I Added a DDASLLogger to DDLog, and logged something. And used "asl_search" to get logs, but got nothing. When I did it on ios7 iphone simulator, I got what I exactly logged. Is it a bug of DDASLLogger?

I finally found the answer just now: YES. It's a bug recording to "asl_search only finds messages with ReadUID set". We need to set the ReadUID property for a message when sending it to ASL. Otherwise asl_search cannot find it.
The code of sending message in DDASLLogger is as following:
- (void)logMessage:(DDLogMessage *)logMessage
{
NSString *logMsg = logMessage->logMsg;
if (formatter)
{
logMsg = [formatter formatLogMessage:logMessage];
}
if (logMsg)
{
const char *msg = [logMsg UTF8String];
int aslLogLevel;
switch (logMessage->logFlag)
{
// Note: By default ASL will filter anything above level 5 (Notice).
// So our mappings shouldn't go above that level.
case LOG_FLAG_ERROR : aslLogLevel = ASL_LEVEL_ALERT; break;
case LOG_FLAG_WARN : aslLogLevel = ASL_LEVEL_CRIT; break;
case LOG_FLAG_INFO : aslLogLevel = ASL_LEVEL_ERR; break;
case LOG_FLAG_DEBUG : aslLogLevel = ASL_LEVEL_WARNING; break;
default : aslLogLevel = ASL_LEVEL_NOTICE; break;
}
asl_log(client, NULL, aslLogLevel, "%s", msg);
}
}
We just need to change
asl_log(client, NULL, aslLogLevel, "%s", msg);
to
aslmsg m = asl_new(ASL_TYPE_MSG);
asl_set(m, ASL_KEY_READ_UID, "501");
asl_log(client, m, aslLogLevel, "%s", msg);
It works. Thanks.

How to convert an image file to base64 string using Arduino UNO or using any other Microcontroller?

Suppose I am in a room which is totally locked and I am begging for the key, so I can go outside. But the person who locked the door behind me is asking to solve a problem for him. The problem is that I have an SD card, SD card module, Arduino UNO, power, a laptop with internet access. What I need to do for the person is that I have to convert an image file stored in the SD card to a base64 string using the Arduino. Now I want to know how to this task for the person, so I can go out freely. Kindly remember the title of this question, otherwise, my life is in danger, and please avoid suggestions only. If you have done this before, then you might answer the question, otherwise please do not. Sorry for being harsh, but it is really bad to have a bad answer. StackOverflow is my last hope.
I have used a library called base64 for Arduino, but I didn't solve my problem. Here is the library. https://github.com/adamvr/arduino-base64
My aim was to convert image to the Base64 string format and then send this string through ESP8266 module to the webserver.
Until now, I didn't find any solution to this problem. I found an alternative to send images taken by a camera. That alternative is a camera module with ESP32-S. This module is "ESP32-S Cam", which takes pictures and sends them to an online webserver.
Here is the code for ESP32 Cam for taking and sending picture to the server where we will have a PHP Scrip given under this code.

int capture_interval = 20000; // Microseconds between captures
const char *post_url = "http://app.softwarism.com/esp32/getPhoto.php"; // Location where images are POSTED
bool internet_connected = false;

How can I open a url in a c++ program

I tried opening a url in my program but I keep getting errors from "shellapi.h", how can I fix it?
ShellExecuteA(NULL, NULL , "chrome.exe", this->photo.c_str(), NULL, SW_SHOWMAXIMIZED);
There are a number of c++ library available for this, and here you can find something.
I have used the following:
The Silicon C++ Web Framework -siliconframework.org
IXWebSocket - https://github.com/machinezone/IXWebSocket
Probably better to just use the default browser, like this:
// assumes photo.c_str() is valid URL ...
ShellExecuteA(0, NULL, photo.c_str(), NULL, NULL, SW_SHOWDEFAULT);
For a cross-platform solution, you can set this header:
#ifdef _WIN32
static int platform = 1;
#elif _WIN64
static int platform= 1;
#elif __linux__
static int platform = 2;
#elif __APPLE__
static int platform = 3;
#else
static int platform = 0;
#endif
and then create a method to open the URL, with the code below:
std::string str;
switch(platform) {
case 1:
str = "explorer";
break;
case 2:
str = "xdg-open";
break;
case 3:
str = "open";
break;
default:
std::cout << "Should never happen on the 3 defined platforms" << std::endl;
}
str.append(" " + url);
std::system(str.data());
Remember to provide a URL string, in this case a const std::string& url.

PIC32MZ2048ECH144 USART- Junk characters transmitted

I am new to MPLAB X Harmony framework and also in working with microcontrollers. I am working on PIC32MZ2048ECH144. I wanted to transmit a simple string using USART and see it displayed in RealTerm terminal.(I have tried HyperTerminal also.) Whatever string I send, I see only junk characters being displayed. When I browsed for the solution for this problem of junk characters being displayed, there were suggestions to check for the baud rate. I have set the baud rate to be 9600 in MPLab Harmony Configurator(Options -> Harmony Framework configuration -> Drivers -> USART -> USART Driver Instance 0 -> Baud Rate -> 9600). So I used the following line in app.c to explicitly set the baud rate.(PBCLK is 100MHz). But no luck!
PLIB_USART_BaudRateSet(USART_ID_2, 100000000 ,9600);
The code for app.c file:
/*******************************************************************************
Start of File
*/
const char *string1 = "*** UART Interrupt-driven Application Example ***\r\n";
const char *string2 = "*** Type some characters and observe the LED turn ON ***\r\n";
APP_DATA appData =
{
};
APP_DRV_OBJECTS appDrvObject;
void APP_Initialize ( void )
{
appData.state = USART_ENABLE;
appData.InterruptFlag = false;
}
bool WriteString(void)
{
if(*appData.stringPointer == '\0')
{
return true;
}
while (PLIB_USART_TransmitterIsEmpty(USART_ID_1))
{
PLIB_USART_TransmitterByteSend(USART_ID_1, *appData.stringPointer);
appData.stringPointer++;
if(*appData.stringPointer == '\0')
{
return true;
}
}
return false;
}
bool PutCharacter(const char character)
{
if(PLIB_USART_TransmitterIsEmpty(USART_ID_1))
{
PLIB_USART_TransmitterByteSend(USART_ID_1, character);
return true;
}
else
return false;
}

/* check the application state*/
switch ( appData.state )
{
case USART_ENABLE:
/* Enable the UART module*/
PLIB_USART_BaudRateSet(USART_ID_1, 100000000 ,9600);
PLIB_USART_Enable(USART_ID_1);
appData.stringPointer = string1;
appData.state = USART_TRANSMIT_FIRST_STRING;
break;
case USART_TRANSMIT_FIRST_STRING:
if(true == WriteString())
{
appData.state = USART_TRANSMIT_SECOND_STRING;
appData.stringPointer = string2;
}
break;
case USART_TRANSMIT_SECOND_STRING:
if(true == WriteString())
{
appData.state = USART_RECEIVE_DONE;
}
break;
case USART_RECEIVE_DONE:
if (appData.InterruptFlag)
{
if(true == PutCharacter(appData.data))
{
appData.InterruptFlag = false;
}
}
break;
default:
while (1);
}

I am sorry that I cannot attach the image of the output I receive in RealTerm as I do not have enough points.
I have no clue where else the problem could be that gives the mismatch of baud rate. Any hints or help would be of great help. Thanks in advance.
Kindly apologize me for any mistakes in the post.
you are correct that it is most likely BAUD rate, but just to be sure how is the USART hooked to the computer? Do you have a translator chip since the computer is expecting +-5V? As for the BAUD, check your clocking scheme and know that PBCLK is sometimes DIV_2 of the SYSCLOCK. There is a great clocking schematic in the Harmony framework to double check your clocking and CONFIG pragmas.

Getting Device ID or Mac Address in iOS [duplicate]

This question already has answers here:
How can I programmatically get the MAC address of an iphone
(12 answers)
Closed 9 years ago.
I have an application that uses rest to communicate to a server, i would like to obtain the iphones either mac address or device ID for uniqueness validation, how can this be done?
[[UIDevice currentDevice] uniqueIdentifier] is guaranteed to be unique to each device.
uniqueIdentifier (Deprecated in iOS 5.0. Instead, create a unique identifier specific to your app.)
The docs recommend use of CFUUIDCreate instead of [[UIDevice currentDevice] uniqueIdentifier]
So here is how you generate an unique id in your app
CFUUIDRef uuidRef = CFUUIDCreate(kCFAllocatorDefault);
NSString *uuidString = (NSString *)CFUUIDCreateString(NULL,uuidRef);
CFRelease(uuidRef);
Note that you have to save the uuidString in user defaults or in other place because you can not generate the same uuidString again.
You can use UIPasteboard to store your generated uuid. And if the app will be deleted and reinstalled you can read from UIPasteboard the old uuid. The paste board will be wiped out when the device will be erased.
In iOS 6 they have introduced the NSUUID Class that is designed to create UUIDs strings
Also they added in iOS 6 #property(nonatomic, readonly, retain) NSUUID *identifierForVendor to the UIDevice class
The value of this property is the same for apps that come from the
same vendor running on the same device. A different value is returned
for apps on the same device that come from different vendors, and for
apps on different devices regardless of vendor.
The value of this property may be nil if the app is running in the
background, before the user has unlocked the device the first time
after the device has been restarted. If the value is nil, wait and get
the value again later.
Also in iOS 6 you can use ASIdentifierManager class from AdSupport.framework. There you have
#property(nonatomic, readonly) NSUUID *advertisingIdentifier
Discussion Unlike the identifierForVendor property of the UIDevice,
the same value is returned to all vendors. This identifier may
change—for example, if the user erases the device—so you should not
cache it.
The value of this property may be nil if the app is running in the
background, before the user has unlocked the device the first time
after the device has been restarted. If the value is nil, wait and get
the value again later.
Edit:
Pay attention that the advertisingIdentifier may return
00000000-0000-0000-0000-000000000000
because there seems to be a bug in iOS. Related question: The advertisingIdentifier and identifierForVendor return "00000000-0000-0000-0000-000000000000"
For a Mac Adress you could use
#import <Foundation/Foundation.h>
#interface MacAddressHelper : NSObject
+ (NSString *)getMacAddress;

#import "MacAddressHelper.h"
#import <sys/socket.h>
#import <sys/sysctl.h>
#import <net/if.h>
#import <net/if_dl.h>
#implementation MacAddressHelper
+ (NSString *)getMacAddress
{
int mgmtInfoBase[6];
char *msgBuffer = NULL;

mgmtInfoBase[4] = NET_RT_IFLIST; // Request all configured interfaces
// With all configured interfaces requested, get handle index
if ((mgmtInfoBase[5] = if_nametoindex("en0")) == 0)
errorFlag = #"if_nametoindex failure";
else
{
// Get the size of the data available (store in len)
if (sysctl(mgmtInfoBase, 6, NULL, &length, NULL, 0) < 0)
errorFlag = #"sysctl mgmtInfoBase failure";
else
{
// Alloc memory based on above call
if ((msgBuffer = malloc(length)) == NULL)
errorFlag = #"buffer allocation failure";
else
{
// Get system information, store in buffer
if (sysctl(mgmtInfoBase, 6, msgBuffer, &length, NULL, 0) < 0)
errorFlag = #"sysctl msgBuffer failure";
}
}
}
// Befor going any further...
if (errorFlag != NULL)
{
NSLog(#"Error: %#", errorFlag);
return errorFlag;
}
// Map msgbuffer to interface message structure
interfaceMsgStruct = (struct if_msghdr *) msgBuffer;
// Map to link-level socket structure
socketStruct = (struct sockaddr_dl *) (interfaceMsgStruct + 1);
// Copy link layer address data in socket structure to an array
memcpy(&macAddress, socketStruct->sdl_data + socketStruct->sdl_nlen, 6);
// Read from char array into a string object, into traditional Mac address format
NSString *macAddressString = [NSString stringWithFormat:#"%02X:%02X:%02X:%02X:%02X:%02X",
macAddress[0], macAddress[1], macAddress[2],
macAddress[3], macAddress[4], macAddress[5]];
//NSLog(#"Mac Address: %#", macAddressString);
// Release the buffer memory
free(msgBuffer);
return macAddressString;
}
#end
Use:
NSLog(#"MAC address: %#",[MacAddressHelper getMacAddress]);
Use this:
NSUUID *id = [[UIDevice currentDevice] identifierForVendor];
NSLog(#"ID: %#", id);
In IOS 5 [[UIDevice currentDevice] uniqueIdentifier] is deprecated.
It's better to use -identifierForVendor or -identifierForAdvertising.
