TyreWiz data field not yet supported

I'm just waiting for the developer to compile it for the 540/840. The other data field - My Bike Radar Traffic (for use with the Garmin Varia radar) that I was waiting for has just been updated yesterday to support those devices.

Same here.  SmartBikeLights updated, My Bike Radar Traffic updated.  Just waiting for DIY #1 & #2 and I'll be set.

Waiting on TyreWiz to be updated too, doesn't show up when I search for it

That's because it's not compatible with the 840 yet.

For the Edge 1040 it took around a month and a half after the Edge 1040 became available in order for the developer to bring an update. I had requested it on Day 1 to the developer.

Hence why I'm wondering if the version from the 1040 could possibly be sideloaded, as it might take some time before an update comes...

I contacted SRAM and they said:

"Our App Team is aware of the lack of current support on the new 540 and 840 and are working on the update."

Sounds promising :)

Looks like alanf has updated the app to work with the 840! It appears on ConnectIQ now. Will try it today

Yup, I just got it on my 840.

Me too, great news :)
