Connecting existing custom PCB to nrf51-DK?

[donbluetooth]

Hello,

I have an existing microprocessor application that I want to test with the nrf51822. I am currently using a different BLE chip. I do not want the trouble of porting my application to the Atmel chip on the nrf51-DK.

Is it possible to directly connect my custom application board to the nrf51-DK and speak only to the nrf51422? This will help me determine how to migrate to this board, then I can adjust my PCB design later.

Thank you,

Port what to the Atmel? The Atmel chip on-board is just a Segger, to provide a standard way to program and debug the chip, plus a UART/USB interface which provides a serial port if you wish to use it. There's no porting to be done there. If you want to you can connect your own debugger to the Debug In header, as long as it's the ARM mini-10 pin header any debugger you like works. And you can connect your board to any of the GPIO lines which surround the board, even the ones used for the USB serial port are available if you aren't using it.
