TrackIt RAK2171 Will not connect to bluetooth after firmware update

Set up my Trackit and it was working. Upgraded firmware and now cannot connect to it via bluetooth. Did something happen during firmware upgrade? I cannot tell. It is still is working but I cannot connect via bluetooth to reconfigure anything. Is there a factory reset for this thing?
thanks in advance for any help.
