Flysky binding

[Topvennie]

I just bought a radiomaster tx16s with opentx companion 2.3
I set up a mode with external RF set to off and internal RF to multi - flysky - STD
Then I press the bind button and power my quad, to put my x6b receiver in bind mode and then I press on bind on my transmitter. It then makes 4 quick beeps and it says binding instead of AETR. Sometimes it switches back to AETR after the first set of 4 quick beeps, sometimes it turn back to AETR after two sets of 4 quick beeps. But it never binds. What am I doing wrong here?

This is an AFHDS2 receiver so that's what you should select as protocol, FlySky is the older protocol.

I don't see the AFHDS2 protocol. Maybe I'm on an older firmware? the module status is v1.3.0.91
The only multiprotocol firmware updates I can find is from a DIY multiprotocol.
When I go into the system setting and then tools, I see crossfire configure, frysky GaSuite, frysky SBEc, .... but nothing that says flysky or AFHDS2

I see it was renamed "Flsky2A". at some point.

DIY multiprotocol is what you have.
