I'm developing with nRF52, SDK 12.2 and softdevice s132 3.0.0. I modified the saadc_ble code from github which uses SDK 11.0. It seemed to work fine. But disconnection happens when I touch the peripheral board. I debugged with Keil5 and got stuck here
I searched the generated map file but still could find the corresponding function.
I did more tests and found that, when I'm using the official DK, no disconnection happens. But when replacing it the PCB I bought online, this problem occurs again.
More information about this. NUS could connect again after approximately 2 sec. But disconnect did happen as soon as I touch the board.
