Is is possible to change from Pi5 with V1.8.1 back to Pi4 V1.7.1? Pi4 V1.7.1 comes up and connects with Android tablet with an own IP-address. I changed this IP-address in Kraken App, the configuration screen comes up but it is not polling anymore. I disconnected power from KrakenSDR and Pi4. On the Android the correct “krakensdr” is connected. Yes, I see another “krakensdr” but with an other IP-address. Must I wait a certain time before connecting power line for KrakenSDR again? Or must I delete some EEPROM values? Something else?
I found the solution. Yes, the change between Pi4 and Pi5 forward and backwards is possible. It is very important, that if a user ends an online measurement session, executes in the configuration screen, section “open system control”, the running system with function “shutdown”. In my case, I damaged two SD-cards, one in Pi4 and the other in Pi5, because I was only executing power off on Pi4/5 and KrakenSDR by deconnecting the power cable. I had to reburn the two images. My call can be closed.
