I see. From a firmware perspective any module is more or less the same (the nRF that it uses is the most important). I suggest you take a look at the resources from my previosu post for how to develop the bluetooth application on the nRF that communicates via UART (with your other MCU).

Thank you for your reply,

I am using the PIC32MX470F512H microcontroller ( PIC32MX470 Curiosity development kit) from this microcontroller I want to handle the BLE module. In my project, the task is to auto-connect paired devices when they come in the Bluetooth module range, and then after exchanging tokens immediately disconnect the device for this purpose I selected this BC805M module and one more reason to purchase this module is it has a higher RX Sensitivity i.e. -97dBm, is there any way to do what I needed in this project, as it doesn't support auto-connect AT-Command it just can advertise itself but can't auto-connect to the paired devices and also one thing I can't change my controller.

Hi,

Reading the initial question, I woudl consider removing the PIC and doing everythign on the nRF. Alternatively, if you need the PIC and BLE connectivity via Bluetooth, you can write a custom Bluetooth application on the nRF that communicates with the PIC via Bluetooht. I suggest you refer to nRF Connect SDK Fundamentals for the basics of nRF development (including UART communication), as well as Bluetooth Low Energy Fundamentals.

OK, Ketil

Is there any alternative way to communicate with the module rather than AT-Command? Can you provide any help from your side?

Hi Krishna

The nRF52805 that's used in this module is delived from Nordic without any firmware. The AT client on the module is made by Fanstel so I suggest you ask them about this.

Best regards,

Ketil
