Might seem like a silly question but are you sure the SRM has battery life still?

I was told when he sold it to me that he'd changed it only a few months prior. I'm being a bit obtuse and can't figure out the SRM software without having one of their own head units to check, though perhaps that's the problem. Is there another way to check that?

When I paired my SRM to a Garmin... I didn't have to manually enter an ANT+ ID.

The Garmin just found it....

Enter zero (0) for the ANT ID where you'd normally enter the specific ID. It's equivalent to telling the head unit to search for the PM.

Less is more.

Yea I know that's how it *should* work. But I also know from other sensors that sometimes, especially if it hasn't been used in a while, that's a good way to get it to pair if the HR strap, PM, etc doesn't want to wake up. But now I can't do that.

This has happened to me sometimes with my SRMs and specific Garmins. For instance, my 920XT wouldn't find it and my Edge 1000 would. I messed around with the magnet position for too long before I found out it was a Garmin problem. Try another head unit first? Garmin's advice after that is to remove all the connected ANT+ device profiles from the device, and re add them. Then, if that doesn't work, you go through the hard reset process

I bet your SRM is dead as a door nail. What's a door nail anyways? They certainly don't transmit an ANT+ signal...

I'd download SimulANT+ (uses a USB ANT+ stick in your PC) and see if the SRM is actually broadcasting. Also, sometimes Garmin head units do funky things when you have a heart rate strap and/or speed/cadence sensors paired with them. Try unpairing any extraneous devices.

I actually unpaired the HR strap already because my experience has always been that it takes longer to pair PM if it's also looking for HR strap and I'm not wearing it. The Simulant is what I was looking for; I've used Qalvin to troubleshoot Quarq on my road/TT in the past, even tried to see if that would work with SRM but no joy. I'll try that tonight, and if that doesn't work, I guess I'll send it off and hope it comes back working.

It may not be wireless. Confirm with SRM if you can find the serial number.

What is the age of the SRM? A possibility is that the cadence magnet is not positioned correctly, such that it is not waking up the SRM and can be tested by removing the SRM and manually orbit the torque ring on the backside of the SRM with a magnet while trying to pair with your Garmin. Failing that, as someone who has replaced batteries in our SRM's, I will say that the battery leads are 32-gauge wires and even with a new battery, if one of those solder joints for the battery leads comes loose from the PCB in the spider, or there is a cold solder joint, then the PCB will not get power. If you are mechanically/electronically inclined (or know someone who is), removing the torque cover would allow you to check the connections, as well as use a digital volt meter to check the battery voltage.





If the battery voltage is way off, and you have the same EVE EF651625 batteries as shown in the image above and are in the US, you can replace them with Harris AN/PRC-152 HUB Batteries.

¯\_(ツ)_/¯

Just to be sure, did you also install the magnet on the BB? If you did not install the magnet correctly on the BB the SRM will not wake up/transmit.
Next, yes when I switch PM's on the same Garmin 500, it can take multiple attempts to get the Garmin to read the new PM. Don't know why this happens. Real PITA. Do you have TrainerRoad or PerfPro (or similar) software that detect new Ant+ devices? If so, you can get the ANT+ # from that.

Simulant+ is showing a "you don't have access to view this file" even after I registered for Thisisant.com. :(
I'm thinking it might be best to start fresh with a new battery anyhow. I'll try pairing again tonight, including with my Forerunner 310 in addition to the 500. If that doesn't work, I'll consider sending it off I guess.

Bumping my own thread because my SRM is back from Colorado with a service report saying it connected to a PC7 fine and has a fresh battery.
Still can't get the damn thing to connect to garmin 500 or 310. Simulant+ required me be a paid member of this is ant to download. Is there ANY other way to figure out ANT+ ID?

IG: idking90

when you got your unit back from SRM, they typically* include a document that lists the work performed. the unit ID is often* on there.

* i'd say "always" as it has been that way every time i've sent in a unit for myself or customers over many years, but i'm sure someone will have one example of when this did not happen.

With a USB ANT+ stick you could try Golden Cheetah in training mode, it has a dialogue to set up ANT+ devices -- AFAIR it shows the ANT+ ID.
