The link diagnostics traced the failure to the RFCOMM channel not establishing on either side, despite permission and pairing — the signature of a BLE-only bond (SPP needs a Bluetooth Classic bond).

FIX ON YOUR SIDE: pair the phone and glasses over Bluetooth Classic in Android settings (not only via Hi Rokid), then retest.
