I'm working on a BLE device that part of its requirements is that it'll only use connect mode between the iPhone and the peripheral (no pairing nor bonding).
According to Apple documentation Bluetooth Accessory
Design Guidelines for
Apple Products
section 3.7 Apple is using Random device address. As much as I know, when using Random device address one need to pair (in order to get the IRK).
Is there a way to have a BLE device who works with iOS and only does connect with no pairing or bonding?

The actual bluetooth pair I am talking about is: let the app shows up in the searching list of Bluetooth of System Settings and other devices can pair to it (like we pair our device to Apple Air Pods).
But all articles I find online are talking about BLE/CoreBluetooth, I don't think these methods could make a device name shows up in the Bluetooth of System Settings.So how to develop an app performing an actual bluetooth pair? Any ideas?
The Bluetooth preferences screen only shows legacy Bluetooth peripherals. Devices advertising BLE services do not appear.
Apps on iOS do not have the ability to create and advertise legacy Bluetooth services.
If you create an app that acts as a BLE peripheral, using Core Bluetooth, and specify that encryption is required for a characteristic then you will trigger a pairing process when an app acting as a Bluetooth central on the other device connects and attempts to read/write that characteristic. Note that this requires cooperating apps on both devices.
We are working in Blood pressure monitor project . we have implemented GATT protocol in our device to communicate with iphone / iPad . so far we are using Core bluetooth framework to communicate with our device ,Its working fine in data transmitting.
But our device is not visible / listing in iPhone Bluetooth in the settings page.
please note that we are not using any MFI chip.
Please advice what we needs to be done to make our device visible in iphone's bluetooth settings page without using MFI chip.
In order for your BLE device to show up in iOS Bluetooth settings, it has to have gone through the pairing process, as stated by Larme.
To do so, the device must have one or more characteristics that are encrypted. When your app tries to read/write/indicate on that characteristic, the read will fail with an Insufficient Authentication error code, which will then should start the pairing process. See section 25.10 in Apple's Accessory Design Guidelines - https://developer.apple.com/accessories/Accessory-Design-Guidelines.pdf
Once the user has selected to Pair in the dialog, keys are exchanged to finish the pairing process. Your device will show up in Bluetooth settings at that point.
Is there a specific reason that you want the device to show up in Bluetooth settings?
I am using a HM-10 bluetooth to pair with my iPhone but I noticed that HM-10 can't be paired with iPhone using the "settings". It just won't show up in my bluetooth list. I will need a special app like "Lightblue" or "Bluecap" to pair it.
My question is, if I need a certain app to pair the bluetooth module with my iPhone, why is that many devices such as bluetooth speakers could be paired using the "settings" even without having an app?
Are there any bluetooth modules that could be paired without having an app like "Lightblue" or "Bluecap"?
Pairing through settings is only available for devices that use legacy profiles such as handsfree or A2DP.
Bluetooth Low Energy devices, such as the HM-10 are discoverable by any app using Core Bluetooth. Apps, like LightBlue, are just general purpose BLE apps that let you explore available BLE devices.
BLE devices only require pairing if they are using encryption on their characteristics. In this case, iOS will show the pairing dialog and complete the pairing process when the app attempts to read the encrypted characteristic.
To use the HM-10 you will need to write your own app to perform whatever communication task you are trying to achieve.
You can use nrf52832 as Bluetooth module.
If you are not making hobby project hm10 is very bad choice
I shifted from hm10 to nrf52832 before 6 months
So my question is can we create an iOS app that can receive data from any bluetooth devices? Even the devices we buy it form eBay?
Any encoding when the data sent from the devices make us can not decode them? Or another description : Can the bluetooth device limit the app that can connect to them ?
Thank you very much.
An iOS app can receive data from any bluetooth device which must confirm the protocol of Bluetooth(GATT, ATT, L2CAP).
Bluetooth device can limit the device to connect by the data format(such as CRC, XOR), the device even can limit the special MAC address of bluetooth to connect if your app not sale on App Store
Below is a simple description to Core Bluetooth, please check the detail Core Bluetooth Programming Guide
The bluetooth device is a Peripheral to produce data, iOS app is a Central that can receive data or send limited data to Central.
When the Peripheral begins advertise, the Central can search and connect to it, when the connection is build, Central can notify or read the Characters in Services of Peripheral
An iOS app can connect to any device that supports the GATT profile with Bluetooth Low Energy/Bluetooth Smart using the Core Bluetooth framework.
Generally, a peripheral cannot prevent your app from connecting to the device, but your ability to read/interpret the data offered by the device will be limited by:
The documentation provided by the device vendor
Your ability to "reverse engineer" the information if documentation is not provided
Any handshake/security methods that the vendor may have implemented; For example the device may require your app to respond with specific data in response to data from the device - see point 2.
Devices that use legacy Bluetooth (i.e. not BLE) are only supported if they offer generic services such as audio - these are supported by the AV framework, or if they are MFi certified - these are supported by the External Accessory framework.
I'm tasked with developing an iPhone app whose first bit of functionality is to connect to a bluetooth transmitting device, receive data from that device, and use that data to do other important things. The issue I'm having is that there doesn't seem to be any good sort of SDK to work with, so I'm thinking of using the GameKit framework to search for bluetooth transmitting devices, connect to the (correct) device, and to receive data from this device.
Bullet points:
- search for bluetooth device
- connect to bluetooth device
- receive data only from the device
Tips/advice?
Apple doesn't let just any Bluetooth device to connect to an iOS device. The device must be MFi compliant.
Assuming you've been tasked with writing the app to work with your company's product, start with signing up with the MFi developer program from Apple.
Assuming the opposite, that you've been tasked with writing the app to work with a third party device make sure the product is MFi compliant. Finding a "Made for iPhone" or "Made for iPad" logo on the device or packaging is likely to indicate it is MFi compliant.
From there you should investigate the External Accessory Framework. Try reading External Accessory Programming Topics
