Basic functional understanding
Dear Sirs,
I've used the SDK to write the code for a proximity-tag (peripheral) with 2 additional custom services. It took some time to understand the right way to implement the latter. But now I've made a start designing the code for a device that must be scanning its surroundings all the time and automatically connect to any one of a number of previously paired/bonded devices. This functionality is displayed by my carkit for instance, but from other forum posts I already understand the HFP is not supported under BLE.
