Hi,
nice projet. I am very interested in it.
But why you are using 5 V and not 3.3 V? The ATmea328 works with 3.3 V too and the NRF have to use 3.3 V.
The only restriction on 3.3 V is the clock limitation for the Atmega (8 MHz). But with no crystal it don't care.
For example you could use an HLK-PM03 instead of HLK-PM01 and remove the linear voltage regulator. So you get more space an everything have the same voltage level.
And another point is, it is recommended to use a capacitor (0.1 µF) to ground for each voltage pin (Vcc, Avcc, Aref).
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:
Raspberry pi
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.
I successfully worked around the issue by updating the /Library/Application Support/Perceptive Automation/Indigo 2022.1/Plugins/MySensors.indigoPlugin/Contents/Server Plugin
/plugin.py script to recognize the internal 21 code.
Here's the diff:
34c134,135
< "GATEWAY_READY" : [14, "Gateway ready", ""]
"GATEWAY_READY" : [14, "Gateway ready", ""],
"DISCOVER_RESPONSE" : [21, "Discover response", ""]
715a717,719
elif itemType == self.getInternalNumber("DISCOVER_RESPONSE"):
# 21 Ignore
pass
P.S. Indigo 2022.1 is complaining about this plugin that it won't be supported in future releases. Is there anyone out there planning to update this plugin?

Hi @acb and others, regarding "Do you know if there is a version of this board that is pad-compatible with the C-versions of these HopeRF RFM69s before I go searching? (Since I believe the C-versions are also pad-compatible with the RFM95s…)" - did you find any alternative?
I'm in the same boat looking for an adapter from NRF24 to the footprint of RFM69*C = RFM95/96.
Thanks, Joost
There are also other solutions that have I2C bus pins on the shield and if you are going to make a battery powered node, I'd suggest to use an I2C sensor as it will be much more battery friendly
