Hi, everyone. I've developed a custom board using nrf52832. I tested it and found that CPU core, GPIO and other peripherals work well, but BLE doesn't work at all. I ran two examples:
- Simple advertiser. I don't see any devices in NRF connect scanner.
- Simple scanner. app_error_fault_handler() is called all time. Argument values: id=1, pc=0x232ba, info=0. I use s132 3.0.0 softdevice.
I double checked all power supply and GND pins and also all external components. I don't think I have any issue with an antenna because I tested another custom device with the same antenna. It works well.
I suspect I have some layout issue, but can't understand what. I checked DEC1 pin on another working device using an oscilloscope and see constant level and small peaks with ADV period.
On my device I don't see this picture. There is constant level 1.1V. I think RF module does not works for some unknown reason.
Could you tell me any useful thoughts based on described information?
