Unstable connection with HRM Run

It seems like the connection interrupts and the 245M gets the data from my wirst until it reconnects again (during a run).

The HR drops from 150 bpm to 125 and then back to 150 for example. Anyone facing these issues as well?

During most of watch alerts (laps, training steps, etc.) my HRM-RUN is being disconnected for a while and drops to 75-76 bpm can be seen. Well known issue with the latest FW 4.40, yet with no response…

Correct, it should be an issue with the FR245. The Garmin Support replaced my HRM but problem was still persistent so they replaced the FR245 as well. Unfortunately with no success. Currently they passed…

Hi,
Garmin pushes update as soon as you use Garmin Express or if you connect thru Wifi.

You can avoid update :

* Removing the GUPDATE.GCD file, in /GARMIN, as soon as the device asks for an update.

+1 – me. 8 to 16 drops per 1h. Mine drops to around 72 bpm. I suspect my FR 245M instead of HRM-Run since I've changed strap in warranty, but the issue still persists.

I wish I could revert to 4.20 or 4.29 (FR 245M), any idea how to get the firmware? cc Former Member

Currently they passed this topic on to the development department in the US. I recommend you not to let them replace your watch as it probably won’t help. Will keep you guys updated.

I have the exact same issue with my Forerunner 245 Music and brand new HRM-Run. Firmware 4.40

Same problem, same firmware

I found the solution for my 245M. See 4.40 run with pulse drops Sunday and 4.29 Beta today.

That’s looking good! How can we change to an older FW version?

Description of the Beta and its installation is here in the Garmin forum: https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-245-series/219208/beta-4-29-available-for-the-forerunner-245-series

Files were not available, I took them here: http://gawisp.com/perry/forerunner/

245M v4.29 http://gawisp.com/perry/forerunner/Forerunner245M_429Beta.zip

If someone uses Mac and 245M the only way to copy files is via 3rd party app. I found Android File Transfer doing the job perfect https://www.android.com/filetransfer/.

NB! Don't forget to switch off automatic updates. You may manually update everything (GPS, sensors hub) but the main firmware.

Thank you so much. I switched off automatic updates on the watch. Unfortunately I can't approve the update on the watch (Installation Instructions Point 3.). The 245M is still showing "Softwareversion 4.40. Do you have any idea how to fix this?
