Concept2 Forum

Hi All,

I did a search and couldn't find anything, so I figured I'd ask.
How do I pair a Coros watch with the PM5 on the Concept 2 Model D?

Thanks for any and all help!

I searched the Coros site and found this:

"Indoor Rowing Mode
"Available on COROS PACE 2/APEX/APEX Pro/VERTIX

"Can’t get on the water? No Problem. You can still use your COROS GPS watch to track your indoor rowing workouts with compatible Concept2 rowing machines (ergometer). Pair the rowing machine with your watch via Bluetooth and start receiving real time data on your COROS watch including Distance, Stroke Count, Power and more."

@Dday5150, I also saw the post on the Coros website that Ripples refers to and I found it to be of absolutely no help whatsoever. Coros has done many things well, but the connectivity for indoor rowing is not one of them! Maybe other indoor rowers, but not the C2. I have yet to get my Coros smartwatch to recognize my PM5. I think that a big part of the problem is that the PM5 is talking the Bluetooth+ protocol, whereas the watch only talks Bluetooth basic. However, you CAN do a partial one-way pairing. If you want your PM5 to receive heart rate data from your watch, you can set your watch to “broadcast HR” mode, then the PM5 picks up your heart rate from the watch. You still can’t get the watch to receive data from the erg workout, however, if you install a 3rd party app such as ergdata, you can then capture your workout, and sync with the C2 online logbook. Your logbook also has the capability to transfer your workout to Strava, so, where there’s a will, there’s a way!

Good luck with your training.

To be honest, that is the exact same level of integration most Garmin watches have, in the same way. So changing the watch doesn't improve things, it probably isn't Coros' fault.

nice unit. Got an excellent review here: https://www.dcrainmaker.com/2020/09/cor ... power.html

Optical wrist HR measurements can be trouble running, corus was good.

"As for the heart rate during that run – it was spot-on with the Garmin HRM-TRI chest strap, save however the first 5 minutes where it completely lost the plot. Totally missed the ‘we’re starting’ boat apparently. Then all of a sudden it locked and off it went. "

Rowing is tougher for optical wrist than running.

Your Corus will pair with and use a HR belt (bluetooth or ant+). If you find your corus reported HR is not reliably tracking the way you want (especially in intervals or transitions like pyramids) you can improve accuracy by adding a belt.

If this is in time for you, try the following method.
On the watch: System > accessories > add Bluetooth
On PM5: Connect
Wait for 10sec, the watch should find your PM5 and you will select it to pair.

For now onwards, the watch and the rower should pair with each other automatically.

To start workout, get your watch into “indoor rower” mode and wait for it to pick up the PM5. I reckon it may help if you go into the “Connect” menu on the PM5 and verify if the watch is connected. Then just row, the signal from PM5 will start to show on the watch normally after 5 strokes or so.

I tried this successfully on 2 of my Apex Pro since last year, hope it works for you!

PS: You can’t pair to your phone’s ERGdata app at the same time due to single BT connection
PPS: the data is captured in full on the watch, and locally on the PM5. I haven’t figure out how to upload the data to ERGdata app / C2 online logbook

This feature stopped working on my Coros2... Seems like a 9mos- year back or so. Not sure who is to blame... likely Coros. Confirmed it worked for a long time like s year plus.

This is Heart Rate broadcast by your watch, not anything tricky or rower unique. Check in your watch options to make sure that you still have ANT+ and/or Bluetooth broadcast enabled. It's usually off by default to save battery, and something may have reset your watch to defaults. I'd use ANT+ so you have bluetooth to connect to your phone -- your watch can only talk to one bluetooth device at a time.

"Broadcast HR via ANT+ connection
Main watch face > press and hold the BACK button to open Toolbox menu > Broadcast HR.
Open the pairing page on supported devices/apps and wait to connect. " https://support.coros.com/hc/en-us/arti ... dcast%20HR.

On the PM5 side, it's connect from main menu then connect HR. It takes a min or two to populate the menu. Think you've done that many times and know it well.

I need to pair my erg data app with the rower so it will upload my workout to the Concept 2 site. Is there a way to also lair my COROS Pace 2 watch?

For anyone curious - I confirmed that pairing works with Coros Pace2/Pace3 with NEWER PM5s (think last 2-3 years). My 5+ year old PM5 stopped working with the watch. This is for the rowing workout pairing that provides distance, strokes, etc...NOT HR monitor as the person above indicated. PM5 has always accepted HR broadcast from my Pace2/Pace3 (although for rowing - you really should use a chest strap for obvious reasons.) I paired successfuly while on business travel with a hotel gym Concept2 with a newer manufacture date and it pulled int he distance info perfectly. I haven't taken the plunge to order a new PM5 head unit to fully validate. I'll just use the ERG app and sync into Training Peaks. The Pace3 still picks up the relative effort through HR for load management.
