Mppt 50/100 smart lost bluetooth after update to 1.6.3, how to reinstall firmware

Hi all,

I updated my 3 x 50/100 MPPT smart from 1.6.2 to 1.6.3. And update run fine but 2nd MPPT lost BT after update. its not showing up on the BT list of tablet or phone and doesn't connect via BT connect. Tried reseting by disconnecting both connections through input and output breakers for 1h and back on, BT stil not working but its operating fine.

The 2nd Mppt shows up under VRM I can see and also enter its setting. Turn on/off BT in its setting doesn't do anything too. It runs and operates fine as i can see via cerbo/VRM fine but BT is completely gone.

How can I reinstall firmware eg also via vrm on this one MPPT...the other identical 2 MPPT all work fine but 2nd MPPT is working fine but lost BT.

Thank you

Christian

Hi @ChrisPI

Just to be clear: the MPPT without bluetooth does show the bluetooth on/off button when connecting via the Remote tab in VictronConnect? Even after power cycling it again?

Kind regards,

@Thiemo van Engelen (Victron Energy staff) yes it shows the BT button even after power cycling but BT seems to be completely gone. As described it’s in VRM and working but I don‘t get a BT signal shown via phone or tablet and BT connect doesn’t show it either.

is there a way I can update this MPPT again via VRM?

Hi @ChrisPI

Normally yes, but this (probably) will not help. There seems to be a problem with the internal BLE module (which is not updated when updating via VE.Direct). The fact that the BLE on/off switch is visible means that the internal communication with the dongle is possible, but somehow it does not provide any BLE signal.

A few more questions:

  1. Did you also perform the original update via VRM?
  2. And again just to be sure: the Bluetooth on/off switch is indeed in the on position?
  3. Could it be that the SmartSolar is visible under a different name in the VictronConnect local tab (something like VE.Direct Smart)

Kind regards,

@ChrisPI It could be that the bluetooth "thinks" it is already connected, and not allowing a new connection.

It would be best to power down and restart. Disconnect PV then battery, wait 30 secs, reconnect battery then PV.

@klim8skeptic i done that already, actually first thing i tried and no change.

But then you would be still visible on the list of BT devices at tablet or phone, you can just not connect to it. But BT is not visible anymore for MPPT2 on tablets or phone. Bt seams to be completely gone on MPPT2.

That's why how I do reinstall the 1.6.3 firmware again on the MPPT? Or a older one like 1.6.2 and then upgrade to 1.6.3 comes up automatically.
