nRF52832 module BLE communication H/W question and disconnect problem question.

[Yclee]

Hello,

I am using nRF52832 DK module(for master), and breakout board(for slaves, 4-slaves).

I have some problem while BLE communication.

First, I am wondering if I can change the H/W setting sequence.

From now, I am power on the MASTER module first, and running the master program.

And power 4-slave module on, one-by-one.

I don't know why, but if I am power on slave module before master module, it cannot be detected.

Is it ordinary method? (because if possible I want to turn on the other slave module first and power master module on)

The second problem is error 0x8 disconnected error.

I have 4-slave module, so as I said above, slave module is powered one by one.

And maybe in that process, disconnected error is occured.

Also, while communication, randomly disconnected.( I set the connection time to 0 )

Is anything I can check or modifying?

Thank you for read my questions.

Best Regards,

Yclee.

Hello,

A common reason for disconnects is when you have runtime error that invokes the app_error_fault_handler() in your application. Have you tried to debug the applications to see if this might be the problem in your case? Also, do you have debug logs from the devices, and where is the '0x8' error reported?
