The SX1262 module doesn’t seem to respond to any SPI commands after waking from deep sleep. This issue has been described in detail, and with sample sketches and verbose debug output in this github issue:
Stick Lite V3 SPI no data after deep sleep wake
Try this example first. https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/tree/master/esp32/libraries/Heltec-Example/examples/LoRaWAN/LoRaWan
This doesn’t help me at all. I’m not using LoraWAN. I’m using just the PHY layer.
Also, the sample sketches attached reproduce it every time.
