i set the service uuid as 0x0 and after i debug the program, i can't find my device. i don't know how to solve the problem. maybe i should not use 0x0? thanks for you help.
i use sd_ble_uuid_vs_add() to add vendor specific uuid firstly, and then initialize the uuid, setting the uuid.uuid to 0x0. finaly i use sd_ble_gatts_service_add() to add service. all of above are in the init function which will be callled in services_init() in main.c file.
