RadioHead VS RadioLib

If you do not use WiFi (though I would) and have to fall back to 433Mhz or similar RF signalling then look at the Radiohead library rather than reinventing the wheel.

These 433 style boards are the ones I would look at (range being a possible limit) - maybe using the RadioHead library and front end the Pi with a dedicated receiver board if you cannot find a compatible Pi library.

You need a networking stack. There are some good examples out there; I remember the RadioHead library from years back. I think someone said it sucks and use this other thing instead but I can't remember what the other thing was. You'd write a driver that performs modulation with the HackRF, then use the rest of the stack to do the packetizing and retransmission and stuff.

As mentioned, chirpstack works well if you still want to use LoRaWAN. Alternatively, you can use a system such as https://www.mysensors.org/ which builds its own protocol on top of lora. Finally, you can write everything from scratch using radio libraries (eg: https://www.airspayce.com/mikem/arduino/RadioHead/)

I have a project where I use LORA with the Radiohead-library (http://www.airspayce.com/mikem/arduino/RadioHead/) to gather data from various locations, and then publish that to the web.

I would take a look at https://www.airspayce.com/mikem/arduino/RadioHead/. I have not personally used this and it is not free for commercial use, but it is one option for providing higher level network functions.

You also need to determine if there is any kind of a conflict between these various packages you are using such as a pin number, etc. See RH_RF69 send hang due to waitPacketSent failed · Issue #12 · PaulStoffregen/RadioHead (github.com) So you need to be able to do testing with status messages to Serial so that you can see those logs.

I don’t actually think this is true. The flipper uses a CC1101 for sub-ghz and this library looks to have implemented APRS with it. https://github.com/jgromes/RadioLib

I hooked up the radios to some microcontrollers and used this Arduino library along with some other custom code.

Hi Insteon friends, I started to work on this in fear that this day might come and actually got decoding of Insteon rf packets working on an ESP32+CC1101. NorthernMan54 has ported rtl_433 to the ESP32 here: https://github.com/NorthernMan54/rtl_433_ESP, however due to limited memory on the ESP32 I had to merge in changes to some of the methods from https://github.com/obones/rtl_433. All of that said, the range of the CC1101 is really short so probably not a viable option (I know very little about RF, so maybe someone can optimize that?). After that I went down the path of using an RFM69HCW which should have better range and using RadioLib https://github.com/jgromes/RadioLib but ran out of time to dedicate to it. Hopefully someone with more RF knowledge can make this a reality. Happy to upload the code that I used for the CC1101.

Your network, your rules. You can use whatever radio parameters you want, and you can use a frequency not used by popular LoRaWAN networks.TTN does not use great parameters for long range anyway. I use https://github.com/sandeepmistry/arduino-LoRa library its easy enough to use and understand. https://github.com/jgromes/RadioLib is good but a bit more complex to implement.

Radiolib seems to used by mature projects I have looked at - Meshtastic for example. The author added tentative support for Pico, although he doesn't have hardware see here: https://github.com/jgromes/RadioLib/issues/361
