N5 Starter Kit - BLE test

[Kingmaster]

Hello everyone,

I'm a beginner and i'm trying to debug a nRF51422 BLE project. The SoC is supposed to wait for commands from a STM32 in order to execute some functions. I have the N5 Starter kit and the STM32f4 discovery board. In Keil µVision, I can build and download code to the flash memory after connecting the N5 module to my laptop using the Segger J-Link cable and a CR2032 coin. While in debug mode, i can see the values for each variable in the Watch window, registers etc ... But I can't interact with it to see which value changes for a certain command. I programmed the correct SoftDevice (S310) with nRFgo Studio and I can also program my application with the generated .hex file. How can i correctly test my BLE project ? Is there a way to connect the STM32 and the NRF51422 via UART ? I can't also use a RS232 terminal to see what's happening because the J-Link driver is not considered as a serial port.

Thanks.

Our SDK uses an error system, so you can use the debugger to check that functions doesn't return an error, that they return 0x00000000 = NRF_SUCCESS.

nRF51422 has UART, so if STM32 also has a UART you should be able to connect them together. I don't have experience with STM32 though.

Another option could be to buy something like this, but this is not something I have tested.
