Hello

I have several P100 switches, all hardware version 1.20, and all on firmware 1.4.9. They all fail to update firmware to the latest offered version, 1.5.5.

I have done a factory reset and re-added them to the iPhone app, they are on the same wifi network as the iPhone (with Mobile Data disabled), the router is a Teltonika RUTx09. When I add the device and the app offers to update firmware, the app sits at “Downloading (0%)” for a couple of seconds then shows “update now”, in a loop. the same is true if I try to update firmware on all devices (only these show up as needing an update).

Please can you advise?

Many thanks.
