Hi Everyone

As the subject mention，

RTT stops working when power is disturbed by motor.

But other fuction that like ble,spi,uart are work well ，

I must cutoff the power and , put on the power again ,the RTT is work.

Any help from you will be appreciate！

What are you using as debugger interface? As the DK is using PCA10040, that chip needs more power to run properly than the nRF chip itself, and you need the debugger chip to run RTT. I am guessing that your motor is drawing too much power to keep the debugger chip running. You probably have to optimise the circuit so that this doesn't occur.

Best regards,
