Have to program two wedding rings with a tiny screen and BLE to detect the other ring is in the neighbourhood and the generate hearts.
The screens are running with the UARTPassThrough.ino example merged with my code and i see them in my phone as two BlueNRGs.
How do i detect the other one is near by?
What do i use?
aci_gap_start_general_discovery_proc(0x4000, 0x4000, 0x00, 0x01); returns 12 which is BLE_STATUS_INVALID_PARAMETER
Can someone point me in the right direction?
Thank You.
