Sonoff RF Bridge IR receive and IR Send problem

[kiralikbeyin]

Latest sonoff.bin uploaded with esptool.py Device 25 SRFB

GPIO5 IR RECEIVE GPIO4 IR SEND also tried GPIO4 IR RECEIVE GPIO5 IR SEND

Didnt send... IRsend {"Protocol":"NEC","Bits":32,"Data":14643343}

No IR receive data on console...

(Hardware is working with OpenMQTTGateway library, both ir send and receive is ok.)

Since there is no information about your setup and all infos from issue template are missing....

[kiralikbeyin]

@Jason2866 you cant make any setup this is not IDE

Terminal command to upload 👍 esptool.py -p /dev/cu.usbserial-A7012RPU write_flash -fs 1MB -fm dout 0x0 sonoff.bin

Status 0 ? Circuit Diagramm wiring?

With this circuit setup you have a very weak sending unit. You have to place the IR diode direct in front of the IR Receiver to get a valid signal... You can use a standard IR remote to check your receiving unit. You get output in console For checking sending unit you can use a old smartphone camera. If it lights up it is working in general

Thanks for your advices:)

Circuit is working very well with https://github.com/1technophile/OpenMQTTGateway

if you dont have a Sonoff RF bridge, someone else can try and see the BUG that IR RECEIVE AND IR SEND is not working for SRFB

@arendst

[Jason2866]

Will try with my Rf Bridge...

[Jason2866]

Update. IR Receive does work. I have no spare IR Diode to test. I see no reason why it shouldnt work to. There is a trap. Keep in mind that labeling GPIO 4 and 5 on Bridge is wrong (swaped). You can read this in wiki.

Another Update. GPIO 4 and 5 are connected to USB. You have to cut traces in Bridge if you want to use GPIO 4 and 5 when powered via USB connector https://github.com/arendst/Sonoff-Tasmota/wiki/Sonoff-RF-Bridge-433#optional-usb-power-while-flashing-the-rf-firmware-hardware-r2-only

[kiralikbeyin]

Very intersting i got codes when powered with FTDI 14:32:55 RSL: tele/sonoff/RESULT = {"IrReceived":{"Protocol":"NEC","Bits":32,"Data":"DF906F"}} 14:33:02 RSL: tele/sonoff/RESULT = {"IrReceived":{"Protocol":"NEC","Bits":32,"Data":"DF10EF"}}

When i connected with USB, no code received as you said.

But i am getting IR codes with OpenMQTTGateway library even its powered by USB. How is this possible i cant understand..

[Jason2866]

TBH i dont know. Cut the traces as shown in picture.

We will add infos to wiki entry Rf Bridge.

ONLY for R2 boards: The R2 boards connect pins GPIO4 and GPIO5 to the USB data lines of the power connector. Compliant USB chargers/power supply are expected to short the two pins together, which is no good. These lines are not used by the original firmware, nor by Tasmota.

The traces toward the USB connector need to be cut to avoid interference by the USB wiring

[Jason2866]

Please close the issue, since your question is solved. Thx

[kiralikbeyin]

ok thanks alot 👍

With this circuit setup you have a very weak sending unit. You have to place the IR diode direct in front of the IR Receiver to get a valid signal...

Hello @Jason2866 , could you point what makes you think this?

[kiralikbeyin]

@1technophile tasmota lib didnt send IR codes but OpenMQTTGateway can send with same circuit..
