thanks for your kind reply.
I will share the debug info.
At the moment, the host is unreachable.
It looks very unstable, wifi side: first I thought it was too far (8m), then reduced to 4m, then 1m.
Still, it dies and is lost from the network.
I had read that simultaneous wifi & bt is not recommended, so I plugged in an USB BT dongle I had around.
Should I have done it the other way round?
Also, the Jivelite interface seems to have problems visualizing the menus (wrong resolution?), and does not show the clock when idle.
I am concerned that the display might degrade, with the same information on all day long.
