Power dropouts on turbo trainer

9807615
11 months ago

I've got an Elite Direto XR-T an I connect it to my Edge 840 and the Elite My E training app at the same time ( with ant+ to the Garmin and Bluetooth to my phone). I've noticed that there are quite a few short power dropouts during all of my indoor rides, but they are only visible on the Garmin aide of things (Garmin connect) and not on the My E training app. So I wanted to ask if anyone else has had this problem with smart trainers and Garmin bike computers and if someone has found a solution to it. 

I'm attaching 2 images (1st one from garmin connect and 2nd one from elite my e training).

    how is your indoor wifi in your room? (2.4GHZ or 5GHZ) . Do you use BT headphone / speakers during the workout?

    I don't use headphones and the Edge connect to the trainer via Ant+.

    wifi in your flat? because it looks like a 2.4GHz signal interference. if the wifi is running on 2.4GHz, on which channel? (must be used the lower range , 1-6 maximum, the #10 is just the ANT+ signal, so if the router is working on the 9,10 or 11 channel, it kills the ANT+ signals.)

    How can I check and possibly change the channel the router is working on? Also the issue is extremely strange because my HRM Dual is also connected via Ant+ and doesn't disconnect.

    Yes true but we live in a very (increasing) noisey RF environment and if Garmin ANT+ can’t hack it then it will become useless. I don’t have sensor dropout issues but I DO have persistent issues between my Garmins (530, 1040) and my Garmin Tacx Snart Trainers (Flow, Flux). They lose the connection to the Resistance control resulting in the resistance not changing when grade changes, a fairly fundamental feature of a smart trainer. Only happens with ANT, does not happen if the Trainer is controlled via the Training App on BT. I have given up trying to do indoor training with the Garmins controlling. I have no other WIFI or BT (under my control) nearby but live in a building with hundreds of RF sources, BT seems to cope but ANT not. Maybe Garmin should allow Garmin devices to talk to the trainers via BT?

    PS I get the connection back by toggling the smart trainer “sensor” disable/enable switch, when it drops it does not give a disconnect message and still shows as “ Enabled” but isn’t , very annoying as it is not always apparent it has happened (until the next few % change in grade) and can do it a few times in an hours indoor riding.

    the HRM is also affected but that is use the last known data for a few secs if there are interferences and you dont see it (or replace the 0 with the last known data as an "error-correction" so it is hiding the problems, the power sensors have no such a correction , obviously) the Bluetooth can jump to another subfrequency if it senses interference is happening so this is why in challenging enviroment the BT is a better choice for sensors. 

    it is depending on your router but at first you need to find out what is the ip address of it (in windows, start a "run"  (win button + X and there the "Run") and type "cmd" and in the command line "ipconfig" and that gives you back the gateway ip address, in this case the gateway is the router, go to the browser and type the ip address like 192.168.1.254 into the web address, and enter and you will reach the login screen of the router. in the settings you can check what type of wifi freq is enabled (older router can work only on 2.4GHz, newer one on both), and what is the channel for the 2.4GHZ( a manual number or auto, if auto, set it manual and select one of the value of the 1-6 range)

    yeah, the x40 series have problem with this FE-C controlling with certain (or all? :) )  (even with the own Tacx models also), the x30 should work good (with Neo or Vortex for sure, the Flux series are the worst Tacx model line, the Flow has more disadvantages than advantages :D), so only the BT controlling is the only stable way (but for this you need a mobile or a tablet or anything else as a Garmin device due to the lack of the BT FTMS protocol...)
