Support for SX1268

Open mph88 opened this issue 1 year ago • 6 comments

Describe the bug The SX1268 does not turn on. The serial output shows that communication with the chip does not occur, as the frequency setting nor gain settings at startup apply. Additionally it reports power on FAILED and the frequency plot shows a flat line. Communication of the ESP32 over wifi, configuring settings, GPS all work ok and unit does not panic and restart during failure to connect to SX1268.

To Reproduce Flashed with PlatformIO using latest dev version.

Expected behavior Chip turns on and is tunable.

Thanks for the report. Yes, the SX1268 is a different chip, currently only the SX1278 is supported. The chips are different, at least frequency programming for SX1268 is different, so I'll have to see if this can be added to the firmware. But unfortunately I don't have any SX1268 for testing. If I manage to get one delivered to Germany before Jan 1st I might give it a try...
