UART pins OpenCPU (nRF52832 SoC)

[amaram]

Hi we are integrating a ANNA-B112 device from u-blox that use the nRF52832 core. The pin mapping for UART appears to be different for the Software (not open source) that they provide by default and the nRF5 SDK. We tried using the default pins 8(RX) and TX(6) from the SDK ... unfortunately it did not help. 

Would anyone know what is the right pin mapping for the UART0 when using the ANNA-B112 device with nRF5 SDK (Open CPU)?

Thanks in advance.

Hi,

You can assign almost any GPIO for the UART RX and TX pin (see GPIO usage restrictions for pins you should avoid), but I guess what you are trying to find out is which of the GPIO pins are connected to the VCOM bridge on your board? I would expect that to be stated in the U-blox documentation somewhere: https://www.u-blox.com/en/product/evk-anna-b112
