debugging nRF51822.

[Bayram ZAYET]

Hello,

My project is on nrf51822 in which I am using BLE and UART interfaces.

There is single UART available on nRF51822 and I am using it for communication with an STM32. Now the problem is to debug the application.

Is there any solution to debug without UART.

I am working on nRF51822, SDK12 & S130 and I have a j-TAG.

Any Idea would be appreciated.

Thanks in advance.

Well, if you meant J-Link instead of J-Tag, there is another option. Disregard the rest of this message if you are not referring to a J-Link.

You can use the Segger RTT-Viewer to print debug messages to a console application. Nordic provides a Segger RTT implementation in a lot of the example projects.

Sorry, you are right Daniel, SEGGER RTT works over standard SWD so it should work on nRF51. I mixed it up with ARM Tracing/SWO (which is present just on nRF52).
