The phyCORE-AM65x SOM features a Sterling-LWB WiFi/Bluetooth module populated directly on-board, which can be ordered as either the 2.4 GHz or the 5 GHz variant. This guide shows you how to use this interface.
For information regarding the hardware configuration for this interface, see the phyCORE-AM65x Hardware Manual.
Run the brcm_patchram_plus utility. This patches the firmware to the radio.
Check that the device was properly configured with the hciconfig command.
Bring the Bluetooth interface up.
Configure another Bluetooth device to scan for available Bluetooth devices, then run "hcitool scan" on the phyCORE-AM65x Development Kit to scan for your device.
Example output when pairing with a Pixel 2 cell phone, where "40:4E:36:XX:XX:XX" is the MAC ID for the phone with the second half redacted:
Use the l2ping command to ping the device using the MAC ID that was printed from the previous command.
Performing the above demonstration may not work as expected with Apple's iPhone products. Apple sets stricter permissions on their Bluetooth interfaces and requires more backend configuration.
