DTM program Setting in debug mode

[wzszzxj]

HI,all:

    How to make a  DTM  program  setting:When I run the DTM program ,it make error in debug mode!  It  goes to nrf_break_cond!

When there are issues with UART on custom board and/or when not debugging, then in most cases it is due to floating UART RXD pin. The RXD pin is used to receive data, and if there is no external circuitry or chip controlling this pin, then it is floating, and a floating input will quickly cause framing errors on the UART. The code may assert in this case. To check if this is the case I recommend to place a >100kohm pull-up resistor on the RXD pin.
