Sonoff RF Bridge with Espurna

I followed this mod:

My board is the R2 V1.0 so made all the hardware mods as per the link above.

Now I got the codes from my remote and had Espurna learn them but I can’t tell if the codes are being sent out from the RF Bridge since nothing is happening when I use the buttons within Espurna’s GUI.

Is there a way to test if there are any RF signals actually coming out if my RF Bridge?

Did you solve the problem?
