nRF52 smart remote 3 does not start without RTT Viewer

[Alireza95]

Hello 

I'm working on Smart Remote custom board, which is based on nRF52832.

My Setup is running very well but only when RTT Viewer is connected.(and advertising led is blinking normally)

If board is powering on without connecting RTT, application does not start and ble is not visible.(advertising LED blinking without any rhythm)

How can i fix this ?

Hello,

I'm not sure what the problem is, but the chip will enter debug interface mode when you start up the RTT viewer so it may be related to that. Do you have a 32KHz on your board, or are you using the internal low-frequency RC oscillator? 

Best regards,
