I tried to connect to the HC-08 Bluetooth module many times but at first, I can't pair module to android and I connect the module to android with Bluetooth Electronics but after the module, I paired I have another issue. I got the below error when I'm tried to connect with the module how can I solve the problem?
Error:
It looks like the HC-08 Bluetooth module works with Bluetooth Low Energy while the Bluetooth Electronics app works with the HC-05 module which is Bluetooth BR/EDR (aka classic). These two are not compatible with each other.
According to: https://drive.google.com/file/d/0B4urklB65vaCcmFqOGRFWV9IR2s/view
The UUID's used by this module are:
Service: "0000ffe0-0000-1000-8000-00805f9b34fb”
Characteristic: “0000ffe1-0000-1000-8000-00805f9b34fb”
I find the nRF Connect app very good for testing these kinds of modules. Or if you have the Chrome or Chromium browser installed on your PC, Phone, or Raspberry Pi, then you can do it from there if you enter the URL of:
chrome://bluetooth-internals/#devices
Press Start Scan -> Inspect the device -> click on 0000ffe0-0000-1000-8000-00805f9b34fb service -> click on 0000ffe1-0000-1000-8000-00805f9b34fb characteristic
You should now be able to read and write values.
