Hi all Nordic developers,
I am currently working on an application using a sensor (the temperature sensor) on a Smart beacon kit, which must connect and send data to a nRF51 DK; for this no problem, i already have done everything using some code (ble app multilink in particular) and it's working. After this, i want the received data by the DK to be sent via UART to the PC, which is of course connected by USB to my DK board. How can i do this? I have already tried to implement some part of the ble_app_uart example, just the part that should initialize the uart service and send data via the function "uart put", but i must be missing something because if i launch it, it conflicts with the multilink part of the code and the DK board doesn't even connect to the beacon, if i comment the "uart_init" function in main, everything returns functional. What am i missing in implementing the UART part? I post the full code, but the uart portion is just the last quarter of the code, i wrote a comment when it starts. Thanks in advance!
