+## Known issue
+
+AT+BLEPHY? and AT+BLECONNPARAM? return startup values cannot be trusted.\
+This is due to the fact these parameters have to be negotiated each time a new BLE connection is established.
+When a connection is establish the host needs to manually call AT+BLEPHY and AT+BLECONNPARAM to set these parameters then it can check the result with AT+BLEPHY? and AT+BLECONNPARAM?
