> Although the unplugfest went well in this regard, it could have been because we "exaggerated" the amount of clock drift. The current BLE controller code does not use an output compare to transmit a BLE frame at a specific time. This could cause the transmission to occur outside the BLE specification. The code should be modified to use the BLE transceiver HW to enforce more exact transmission timing.
