Hi I'm looking forward to hear if I could program an nRf51822 QFAA without using the development kit/board. The chip I have currently is a N51822- S4AT, from Wireless Tag Technology which comes programmed with some AT command set to start with. I want to program it with a simple UART/Serial program with the S130 v1.0 softdeviceimage description(/attachment/d786981f86f3f28d7dccb59576254286)(/attachment/2a9d901324aac7a9afaec31b0971bfb0).
I have a blackmagic probe that I used to erase the chip (arm-gcc) and load the s130 v1.0 hex from SDK 7/8/10 (tried all) and then use the mbed online compiler to generate a hex for UART application. But I couldn't see any data coming out through the serial port (I have tried both using a Serial software and logic analyser).
I have also read about 16Mhz and 32Mhz crystal could possibly affect the timing and not transmitting any packets/data out?
I could see the application on the nRf connect phone app and connect to it and send data and see the conversion of bytes in the log. But I couldn't see it on the serial port?
Please advice?
Thanks nar0909
