Hi. I’m trying to install ESPHome on a Sonoff RF Bridge R2. Installation seemed to be proceeding well. The bridge is connected to a Raspberry Pi running HA via a USB FTDI TTL serial interface. Connecting to the device is working (after setting it in programming mode). But “download preparation” fails and the log is fairly cryptic.
INFO ESPHome 2025.3.2
INFO Reading configuration /config/esphome/sonoff-rf-bridge-r2.yaml…

I am guessing that the log means that the C++ firmware was compiled and linked but failed to transfer to the bridge.
I’d sure appreciate any thoughts on where to go from here.
Thanks.
