Hi everyone, I have one question shown in the title. I try to add a second service in "ble_app_uart" project (the project is in the SDK for nRF51, SD130 v2), I did not change any code in the original project but only add a new service I learnt in this blog: devzone.nordicsemi.com/.../ . Then the program seems just stop and fail to add even one service. It works very well before I add the second service. For a little bit more detail, I put the second service init code in the original services_init() function. And it works with my own service when I bypass the original service. My board is PCA10028 Any idea?
