#25025·Tasmota

No support for 0xA6 RF command in iTead protocol implementation

Author: szymorCreated Sep 12, 2026Updated Sep 12, 2026

PROBLEM DESCRIPTION

A clear and concise description of what the problem is. In xdrv_06_snfbridge.ino 0xA6 RF command support has not been implemented. There are claims that it is supported by Portisch firmware only, however the RF chip flashed with the original firmware clearly supports 0xA6 RF command, which was redefined by Portisch. The original 0xA6 RF command (AA A6 55) allows to cancel the code learning process before timing out, as described here.
