In general, yes, the MySensors framework (library?) should support FOTA a couple different ways (read more at link). Were you aware of this, or is there some problem with your particular hardware?
@NielBierman said in FOTA possibilities for remote sensor network:
I don't know yet whether you even need to change your gateway from microcontroller (uC) to Single Board Computer (SBC) or not. However if you do (or are looking for a controller, or whatever), by all means, please do yourself (and all of us) a favor and do a little more research as there are lots of better options out there for SBC nowadays, than RPi!
For me, uC have been fine for gateway although I do use some SBC for controllers, MQTT broker, and various other GNU/Linux based servers/services and they are wonderful for that. But perhaps your needs are different from mine.
Hard to say. St:fail generally means that you don't get ack from the receiver. This is normally range, power or hardware. There is not a general fix for this but you need to try and learn... i admit its strange I worked for some days. Maybe a radio fried ?
Don't have the radios to close to eachother. Try a.couple of meters.
Sorry I'm out of more solid ideas.
Hey sundberg84, quick question for you.
If you look at my debug logs above it looks like the gateway is infact receiving the message but the node thinks it fails. Con you confirm my interpretation of the following two lines?
send: 42-42-0-0 s=1,c=1,t=0,pt=7,l=5,sg=0,st=fail:20.0
0;255;3;0;9;read: 42-42-0 s=1,c=1,t=0,pt=7,l=5,sg=0:20.0
If that's correct, could that change what the issue might be?
Yes, I saw that - it seems to work one way but the ack (return) does not reach back. So its on the edge.
But this should update the value in your controller.
