Bluetooth and ZigBee devices are working or pairing within its own family devices based on parameters such as network layers, security algorithms, etc... I want to write an application to make a communication between ZigBee and Bluetooth device. Is it possible?
You would need to create a gateway between the two networks. Your application would need to interface with a ZigBee radio and a Bluetooth radio, join each network, and then proxy communications between devices on the networks.
What devices do you plan to bridge? Your application will need to appear as device X on the ZigBee network, and device Y on the Bluetooth network and convert data received to the correct format to send out on the other network.
If it were kept simple, something like this could work. A module that is a Zigbee presence, with a pairable bluetooth node. If a bluetooth-paired device comes near, the Zigbee announces itself as 'present'. When the bluuue tooth paired device is no longer around, the Zigbee device becomes "not present".

I am doing my FYP and for this I need some information:
Is it possible to connect a mobile with a LoRa Network via cellular SIM?
Actually, I want to build a mobile software that will operate with a local LoRa network, and the user can connect to the network using this app via cellular network.
No, LTE/GSM/EDGE/Mobile network is a different transmission method than LoRa and thus can not connect to LoRaWAN networks.
No I don't think you can . But I think you need another module to include in your project to handle the SIM part and that way you can switch between the Lora and SIM
I am able to set up communication between multiple devices using NSNetServices class but only when those all devices are on same wifi network. Is it possible to make all the devices communicate regardless of the network availability, means it shouldn't matter if they are connected to same network or not connected to any network at all, just their wifi and bluetooth is on.
And I don't wanna do it using MultipeerConnectivity framework.
If probe response packets announces the capabilities of a network,
then what is the purpose of Beacon frames in wireless 802.11 ?
Among other things, beacons allow a device to passively scan all channels for available Access Points so that a list may be presented to a user showing signal strength. They also allow a device to detect if there is another Access Point on the same network and presumably on a different channel with a better signal.
I am looking into building some apps for bluetooth accessories, and wanted to know if there was some sort of device that could do the following (for sake of simplicity, lets call the "wi-fi to bluetooth" transmitter the "dongle"):
Dongle can connect to a wi-fi network, mobile device then sends a command over wi-fi
Dongle receives command from wi-fi network
Dongle then converts those commands and transmits out as bluetooth
Bluetooth accessory then receives the converted commands from dongle
I am not sure if such a device exists, but I have some great ideas for building apps that could remotely access bluetooth accessories over a wi-fi network.
How does euclid analytics (http://euclidanalytics.com/product/how/) get the mac addresses of nearby smartphones? (Turning wifi ap into a smartphone sensor !) Do I need to do some instrumentation work on the wifi AP? Or is there another way can achieve the same goal?
if you can sniff wireless packets, you can see every wifi device, what is communicating ( except if its in sniffer mode too ), so basically they scanning for wifi signals, what you can see, but just if wifi and scanning is turned on the phone.
take a look at Kismet
but you myght need a wireless card what can go into sniffing mode
