Description

Ordered two LILYGO® TTGO LoRa32 V2.1_1.6. They would message each other just fine. Formatted and inserted a 16 Gig SD card for each. The Web Page/192.168.4.1 would not mount. I tried everything short of re-flashing. After pushing the RESET Button on each, they worked as expected, did not have to push RESET Button again for them to message.

Contributor guide

Research direction
Examine the TTGO LoRa32 schematic to identify the SD card detect pin (typically GPIO 2 or 13). Implement an interrupt service routine to monitor that pin and trigger the SD card mount function when a card is inserted. Verify the mount logic in the firmware to ensure it can be called repeatedly.
