Sorry for the very late response. I missed this issue:

WARNING: MCU version mismatch (expected:01.00.00, got:V00.02.06)

This explains the issue. You need to update your MCU firmware. See also: https://github.com/Lora-net/sx1302_hal/tree/master/util_boot

Note that if you are using the latest ChirpStack Gateway OS, then you can perform this upgrade using the web-interface:
