I've been getting some work in on the esp32-lora driver (in addition to moving to self-hosted git) and happy to report it can happily handle at least two devices! Basic testing of having one device send and the other receive works as expected, though this wouldn't be the expected operating mode. This turned out to be fairly straight forward, at least in part due to the esp-idf handling bus sharing, though it also required FreeRTOS Semaphore locking as suggested by the esp-idf development guide. With these changes I've also dropped all KConfig based defaults as they don't play well with multiple devices and even cause confusion when expectations are to 'just work' (looking at you Arduino). This means the driver will no longer abort (via assert) if the config is wrong and return an error code instead.
Hardware Revision 2
This has been started, so far it's mainly adding breakout header for the remaining GPIOs, all 4 of them! Some things have been rearranged in an effort to make assembly easier. I'm also intended to add #SOICbite Programming/Debug Connector Footprint to lower the cost/assembly time of non-development boards. Sadly I still don't have anymore insight into the reset issue but I will certainly assemble the last two boards before sending out Rev2.
