Steps to setup the communication of rasp pi 3 with hm-10 installed on tm4c microcontroller

Thu Sep 12, 2019 6:10 am

I would be happy if anyone could give me a hint, because surprisingly I couldn't find any source where the Pi setup for hm-10 is explained, my question is how to setup the Rasp Pi 3 to connect to hm-10 over bluetooth and send the commands?

My current setup as follows, hm-10 is installed on breadboard and the pin connections are going to tm4c microcontroller, now I am trying to communicate rasp pi 3 with hm-10 over bluetooth in order to send the commands to hm-10 from rasp pi.

Please help, because I am really stuck on this issue for several days.

First step is to see if the Pi recognizes the HM-10. Use the bluetoothctl command 'scan' to see if the device is recognized. If so, you can use bluetoothctl or gatttool to connect and read or write characteristics.

That's assuming you have a valid BLE service and advertising running on the TM4C. You didn't mention that.
