NRF52DK. NRF_BREAKPOINT_COND (ERROR 4 [NRF_ERROR_NO_MEM]).

[Sergeant]

Hello. 

I get an error NRF_BREAKPOINT_COND. I use nRF5_SDK_17.0.2, s132_nrf52_7.2.0_softdevice and my kit - nRF52-DK. 

An error occurs when trying to swap UART pins (Change  RX_PIN_NUMBER 3 (8) and  TX_PIN_NUMBER 4 (6) )  in example nRF5_SDK_17.0.2_d674dde \ examples \ ble_peripheral \ ble_app_uart:

What needs to be changed in the project so that the error does not occur?

Thanks.

Thanks Kenneth!

I connected from my phone. In Now there is a message: Data len is set to 0xF4(244)

How to fix it?

Hi 

I have exactly the same problem.
ERROR Code is 4 (NRF_ERROR_NO_MEM).
Perhaps, only the nus(ble_app_uart) example has the same problem.

I also pulled up the RX pin (on an oscilloscope, it's high), but that doesn't solve the problem.
Also, even if the USB to UART Dongle is connected to the corresponding pin and connected to the PC (in this way, the RX pin remains high), the problem is not solved.

Do you have any other solution other than pull-ups?

[Kenneth]

Please create a new case, and also specify which api that return NRF_ERROR_NO_MEM.
