I have problems updating the RaspBee 2 FW to the newest version.
Al Firmwares later than 26690700 does not work. Not work means the device is not shown in “Phoscon APP”, it always says “Hersteller / Manufacturer unknown” and “Firmware: nicht verbunden”.
I use the headless raspi image version provided on Phoscon Website so I’m currently not able to start GUI. But I will try your suggestion and report my findings here.
with the GUI-Version of Raspi Image the Flash to the newest Firmware showed a fail, but the Phoscon App could now access the RaspBee 2 with the latest firmware
There is a bug in GCFFlasher that can wrongly output the “failed” when checking after writing. So this is just a display error. This is fixed with GCFFlasher 4 which is on the way.
As long as the Phoscon app shows the firmware and devices can be added and can be used, everything is okay.
