I got a replacement 105 di2 rear derailleur that I'm trying to pair up to my Wahoo Roam. Because it's a replacement, I unpaired/forget the previous di2 so I can pair the new one. However, the Wahoo is not finding the replacement di2. I've made sure the di2 is not sleeping. I also tried to pair it with the di2 in pairing mode (usually reserved for the E-tube app). All nothing. The di2 does connect to the e-tube app so that makes me lean more towards the Wahoo.

Any thoughts/suggestions? Thanks!

Are you able to see the new RD in the E-Tube app.
Maybe check it's firmware revision at the same time.
Don't forget to "Disconnect" correctly.

Yes, the RD shows up on e-tube and all good there. Firmware is updated.

Then as long as the bike is awake (trip the brifters) the wahoo should be able to add the Di2 as a sensor

Thinking about it….. Bluetooth operates on 2.4GHz, make sure you are not near other 2.4GHz devices.
Anything Wi-Fi, Microwave oven, phone…..

Go outside if you have to

probably have to pair the phone to the wahoo to have it see the Di2

I've not had to do this with my 8000 11sp or 8100 12sp Di2.

Wahoo is paired to phone through elemnt app. I tried to pair di2 through elemnt app and also directly through the roam device. both times, it doesn't see it. So strange. I do have multiple devices nearby though.

will the wahoo pair with another sensor if you "forget" an already existing one known to recently work with it?

howaboutme

Good suggestion. I'll try that. Thank you.

howaboutme , I put a lot of configuration into my Bolt before I really understood the pages, etc. My configs were logic spaghetti and doing a factory reset is what allowed me to add a new sensor.

You're probably not as dumb as me, but the factory reset was the enema my Bolt needed. It's been very happy ever since.

Thanks for your experience. Does a factory reset affect the history/previous stats already saved in the Element App? A factory reset seems to be an easy solution if nothing works.

The reset wiped it clean.

howaboutme

Ok thanks. Luckily, I only have 3 rides on it and all of this is backed up onto RWG and Strava. I'm assuming that when they sync, it doesn't wipe previous data? I'm new, so I don't know or can't assume anything.

Since you use Element, your ride data is in their cloud too. Only the configurations are lost in the reset.

Not usually. The OP has the Shimano wireless transceiver (he's had a pairing previously) , that pairs directly to the shifters.

howaboutme

Ok all. I unpaired the Wahoo Cadence sensor to see if it will find it and repair. It did. So now I'm thinking it's the di2? Any thoughts? Should I do a factory reset of the Wahoo just so I can fully eliminate that as a cause?

I also confirmed that it can connect to the E-Tube app. I even tried it in pairing mode just in case. Nothing.

howaboutme

Ok, I did a factory reset of the Wahoo. Every sensor was found and paired except the di2. Any thoughts?

howaboutme

I figured it out!! The di2 was only set to bluetooth. It needed to be set to both Ant+ and BT.

Well that’s a new one….

Thanks for reporting back on the fix.
