Power2max powerbox crankset issue

Just curious to know if anybody else may have experienced the same issue.
I’ve had the power2max Powerbox crankset for quite a while and it’s never given me any issues. I also paid to unlock the Bluetooth feature. A while back their app updated and provided a free trial of the left right balance feature for 30 hours of riding, so I went ahead and did it.

Yesterday my crankset would not connect via Bluetooth, but I could still get ant+ connection. (I much prefer the Bluetooth so I can use my phone to train and my laptop for entertainment)

I suspect this coincided with the 30 hours of left right balance expiring, but I’m not completely positive because I don’t remember the exact day I activated that. Just curious if anyone else may have experienced the same thing. I did contact their support but haven’t heard anything back.

TL/DR- activated left right balance free trial on my crankset and at completion of that Bluetooth stopped working too.

Have you tried pulling the battery for a hard reboot?

Yeah, a pulled it for a few minutes, and then afterwords a couple of hours to no avail

contact power2max

I’ve already spoken with both power2max and FSA, not the type to just jump on a web forum and ask questions without thoroughly troubleshooting first. just trying to see if anybody else had the same issue and was able to resolve, or knew of another way to reset perhaps

unfortunately I don’t know of any. I have the same pm on a bike, but didn’t do the freebie. haven’t come across your issue.

try a fresh battery. also see if the app connects, that uses BT. So, if that works then it has to be something with the setup and would talk to power2max again.

some devices can be reset by shorting the battery terminal with a screwdriver or something conductive to connect the positive and negative battery terminals. ask p2m about it.

you have to be patient in the time of covid. afaik, they are pretty small and in normal times takes a day or two for a response.

Thanks. I did try the new battery and was able to talk to both companies- to no avail yet. I’ll try shorting it just to test it. I wish I could at least connect to the app, but ALL Bluetooth communication is completely shut off. :disappointed:

oh, that sounds bad, good luck.

I can’t connect to my PowerBox PM from the P2M app anymore either (via Bluetooth, don’t have ANT+ on phone so can’t test that). Stopped working a few weeks ago I guess. I haven’t paid for any upgrades or anything like that so I’ve never used it with BT, just ANT+ to head unit. So maybe there’s an issue with the mobile app as well?

did you check on P2Max websıte that if BT is still enabled?

Yes. It is. And either way it should connect via Bluetooth to the app, upgrade or not.

Interesting. Thanks… hoping it’s an issue like that.

I’m able to connect with my power2max app as well as the TR app. I have purchased BT a while ago as well, and the latest firmware that was issued for it (still pretty old even though it is the latest).

interesting. My NGEco stopped connecting via BT just a couple of days ago. Never had any issues via BT. I’ve tried pulling the battery and putting that back in and that seems to work ok. Might try a new battery next time, but odd to see others are having issues with BT connectivity as well

Are you on Android or iOS?

iOS.

Hmmm. There goes my theory that it was due to an iOS update breaking the app.

It’s likely connecting to something else. Likely your app. BT only connects to one thing. Turn off your phone.
