Mppt connection fails

My Smartsolar MPPT 75 10 fails to stay connected to the app for longer than a few seconds. It hasn't been a big problem until now that the firmware needs to be updated (without reason)...

Now I have little use of the unit because it won't work at all, when connected I only come to the message that it need to be updated, and it fails at around 60% when I try.

maybe your smartphone device needs to turn off and restart, then try update with device in close range to the MPPT unit
