hi...
What are the things I can check if I can't find my nRF51 upon scanning for BT devices? I am using nrf52832 and can successfully program the device via a Segger J-Link...
Simple and perhaps stupid, but important for me: the reports of detected devices I see in nRFConnect (desktop or mobile version) are based ONLY on BLE advertising packets...
Hi,
I am experiencing problems with the app_error_handler function defined in app_error_handler_iar_c provided with the SDK V15.0.0.
