LED Control about rf-bridge-efm8bb1 HOT 5 CLOSED

No, only the red one. The LED will be switched by RF signals.

from rf-bridge-efm8bb1.

in this firmware hex file is a demo to flash the blue LED.
maybe that helps?

Only a hardware hack will help:.

The green one is power, the blue one controled by the ESP and the red one by the EFM8BB1.

sorry, my mistake. Many thank you for the information.
With this information I can control the blue LED from the esp via GPIO13.
Like:
pinMode (13, OUTPUT_OPEN_DRAIN);
digitalWrite (13, LOW);
delay (1000);
digitalWrite (13, HIGH);
delay (1000);

thank you

Am I correct in saying that the red LED is indeed controlled by this firmware? And if so, would you be open to a PR implementing this in the form of a command from the host? I might give it a try.

I've got my RF Bridge in a visible location (needs to be there for signal reception purposes) and with a hardware hack I've managed to control the green Sonoff logo LED (connecting it to GPIO12 via a 1k resistor), the blue LED is already controllable and defaults to off (unless there's a warning in ESPHome) so now only the RF LED remains.
