nrf51822 Debug

[Milan]

Hi Team,

My application is based on nrf51822 SoC in which I am using BLE and UART interfaces.

There is single UART available and I have used it in communicating with other serial device. Now the problem is to debug the application.

Is there any other way/idea?

Do you have access to the SWD interface pins ? You use the SWD interface with a Jtag tool such as J-Link or CMSIS-DAP for Flashing & debugging.

Is it a custom board? Which pins do you have access to?

[Milan]

Yes, I am planning to make a board for my application with nRF51822 SoC. I am worried that I won't have UART for debugging as UART is already busy communicating with other device.

Any Idea on this?

[Milan]

I have access of SWD interface but I don't have UART for normal debugging without J-Link.

Hi Team,

Is there any other option to have debug? Something like implementing UART on normal GPIO pins? Or any other idea.
