Forums - iBeacon demo with QCA4020

We dont have any demo showing iBeacon support.
However, QCA4020 QAPIs support standard BLE protocol hence application developer can take care of implementation of iBeacon using application note from Apple.

iBeacon code example below for anyone who cares...  you will need to replace elog() function with your own.  Dr. Wolfe
