Hi, got an interesting problem, this is on a custom board with nRF51822 QFAB that we are bringing up. The radio test (not using softdevice) works ok and produces strong transmit signal (as strong or even stronger than from the eval board). However none of the BLE/softdevice examples work. What can cause this? How to troubleshoot?
Is there anything different that needs to be done because this is one of the AB (128k) chips?
Is there any basic self-test that allows to check that softdevice itself is flashed and working correctly? (correct memory map, calls go to the right functions? etc) This is as opposed to testing that the radio hardware is working ("radio_test_example" ) or that BLE is working ("ble_app_dtm" )
