Feature: Support RFM96 LoRa chip

[petrkr]

I have custom board which using RFM96 modules. Since RFM96 is quite similar to SX127x there should not be lot of changes. I just making this as placeholder for future work on it.

I wanted show it today, but it does not work out-of-box, so before I will forgot I will make this as placeholder to remember.

now I am in boot loop

Inspiration for example in Meshastic https://github.com/meshtastic/firmware/blob/master/src/mesh/RadioLibRF95.cpp

So this is a "new" (old) board to add to tracker possibilities , right?

It seems that I runs over Radiolib and the pinouts are similar to sx1278 boards

do you have success using it on any custom code (not meshtastic?) to validate this fast?

[petrkr]

Something like that. I have development boards before ttgo or others existed and I make break out board for rfm9x modules. And since I wanted to show aprs to one friend, who asked for it. I decide to try it on mine board as I have them and do not wanted wait 1 month for aliexpress one.

I used those boards back to 2018/2019 on TTN lorawan and later on HNT/Helium

Here I was using LMIC library with it https://github.com/petrkr/helium-lora-sht3x

which pins definitions change did you change on yours to make it work?

or what did you try (and change) to know where to start(over)

[petrkr]

Here I did fork and created new board definition

petrkr@0752172

this fork got the reboot loop?

but did you upload filesystem? as Lora pins definitions dont produce reboot loops :P

[petrkr]

Filesystem? Nope :)

Time to read carefully build instructions. I had like half hour, so I did platform build and upload.

Now I am on way to HAM meetup. I will maybe have some time there too.

Well. Bootloop fixed, really flashing filesystem helps.

But for now really does not initialized that LoRa Radio

time to revalidate pins definitions on pins_config.h

[petrkr]

I have to test some test code for that module to check if module itself works. Pinout is fine, checked again.

I have to check how to add some more debug output/messages. So I can try RAW SPI messages.

Anyway thank you

let me know how the testing goes, to add this also as a valid board later ;)
