can't bind s6r with new fw

Ok, I updated to Otx 2.3.5 and firmware for my QX7 to 2.3.5. I updated my s6r to 2.1. Now I can't get it to bind. Maybe I'm not doing the procedure correctly. I put my tx in bind mode (1-16 and 1-8 tel.) Hold the bind button while plugging in power. Green light comes on and a quick red flash, unplug power then release button. Then exit bind mode on tx. Plug power back into rx and I get a flashing red light. This rx was bound to this tx before reflash. I have another s6r that I have already bound to this tx with previous tx firmware (2.2.4) that works still with tx update so I know the tx is good. I hate to go back with rx fw but I might have to. Any help?

Sounds like you haven't updated the Tx module.

This is OpenTX firmware, but to use receivers that run 2.1 what you need is to also update the radio's internal RF module. Similar to the receiver, get the firmware for that as an frk file from FrSky's website.

OK, now I understand. I have updated tx to 2.1.0 but updated my rx to 2.0.1. If I understand you right they must be the same version. There is no 2.1.0 for the sxr. So do I have to flash my tx back to 2.0.1 to match the rx? I didn't realize the numbers were different sequence.

Yes the versions must match. I believe the 2.1.0 for SxR is still under testing.
