@Bjorn We didn’t hear anything back from Teltonika Team till today and to be honest have given up on deploying the TRB500 Range of devices at our clients. We won’t be getting any new Teltonika Network devices as well. (GPS Series from Teltonika on the other hand is still heavily in use with us)
The TRB500 is a lost cause… we had even worse problems with our test deployment where the 5G NSA completely stopped working after an update and the auto updater was completely broken. Choosing a stable release still updated to the latest… unacceptable…
You can check our other Post here: TRB500 - 5G NSA not possible after upgrade, 5G RSSI N/A, Type jumping between 5G and 4G+ - #2 by svgyda
One TRB500 is still in our test deployment and stable IF we run FW 00.07.19.4 and NAT Mode. Then the full capacity of our provider can be used. Everything else and the TRB500 is a bottleneck.
Let me know if you find out anything new or Teltonika R&D will get back to you, as we are sitting on multiple pieces of TRB500.
