Hey guys,
I'm working with a Laird BL652-DVK (nrF 52832 - chip), Nordic SDK v.14.2.0 and SES (Segger Embedded Studio v.4.30). I am trying to combine the examples ble_app_uart and ble_app_hrs. Both examples are working separatly. But when I build my program, I'm getting "undefined reference errors" and I don't know why, because I changed my paths, config-file and makefile.?
For better understanding: I worked with the program ble_app_uart to send datas and string but that works only for the nordic app (phone and pc), because "pairing not supported". To send and receive datas and strings to a central ble modul (not programmed in C), I want to use the peer manager for the data communication and use the example ble_app_hrs as reference. Maybe someone has another idea to solve this problem?
Here is my main.c:
