It’s not great news on that front :-/ Here’s the full blurb I got:
“I haven’t been able to interface the Torch LoRa with any other LoRa in testing so far (which from my previous experience, is somewhat common with LoRa). This is likely due to our aggressive frequency hopping scheme (FCC Compliance requirement for 1 Watt TX) and in-house firmware. The only answer right now is “Buy one and see if you can make it work”. I could likely supply them with the firmware binary we use on the Torch LoRa (STM32WLE5CCU6), but it may be very tricky getting it to interface with the STM32WLE on a breakout board”
Most of our stuff is out of stock at the moment Search Results for lora - SparkFun Electronics …but maybe something like https://www.digikey.com/en/products/detail/sparkfun-electronics/WRL-15836/12178425 could be worth a shot? It would at least lend itself to being generally customizable (robust libraries)
