I acquired the two subject boards from SeeedStudio in order to create a low-cost LoRa device. The two boards conveniently connect via their B2B connector which should make life easier. What I can't find is an Arduino LoRa library that will work with the boards. I suspect the SX1262 is the biggest issue, since the RadioHead library does not appear to be compatible. Any suggestions? I'm looking at an application that can send and receive LoRa messages (not LoRaWAN).

An Internet search on 'arduino sx1262 library' will find more.
the challenge has been to find one that will work via the B2B connector on the subject boards. I may simply have to add a header to the Wio_SX1262 board and then wire the two boards together. However, once I solder on the header, I can't use the B2B connector if I learn how to instantiate the radio object.
Thank you for your references!
It's not the case ... at last according to this :
https://github.com/jgromes/RadioLib?tab=readme-ov-file#supported-modules
RadioHead and RadioLib are separate libraries.
Sorry for the confusion 
Radiolib is now OK for LoRaWAN , is use it with TTN ... but ctmorisson is looking for LoRa (point to point) with SX1262
Actually, I just realized the RadioHead library works on one of my Heltec devices that has a SX1262 radio. Hmmmm....
The newest version does, not tried it myself.
RadioHead support for S126x is fairly recent, and I seem to recall that early versions did not support the busy pin.
I have used the SX12XX-LoRa library referenced by @srnet in post 2 for LoRa P2P with the SX1262
@horace @srn @ctmorrison @al1fch I just did it yesterday for the Seeedstudio XIAO-esp32s3-sense with wio-sxx1262 using the RadioLib but with some small changes and the correct connections through the B2B connector. here is the code and an explanation.

I would like to do a lot more with this board. I think someone mentioned they got LoRaWan working. I would like to be able to do that with the Arduino IDE. I also feel that some kind of arduino IDE send receive with Meshtastic would be useful. If anyone has ideas please post.
I used the example code from https://github.com/HelTecAutomation/Heltec_ESP32/blob/master/examples/LoRaWAN/LoRaWan/LoRaWan.ino to connect to TTN V3 server using LoRaWAN using a Heltec_WiFi_LoRa32_V3
