Change bluetooth password on V8

Recommended Posts

Hi,

Did anyone manage to change default bluetooth password on Inmotion V8 sucessfully? This should be possible via app (with registered ownership). I have no idea how to change it as options described in manual (attached) simply are not to be found anywhere (yes, I am owner, yes latest firmware and app from google play).

Inmotion support in China were able to help me with some other issues, but on the topic of bluetooth, due to lack of knowledge or proper understanding in English their answer is " Sorry, you can't change your Bluetooth password because Bluetooth does not require a password. Please don't worry, this will not be dangerous" does not really help. I tried to explain it the best I could few times. Well the bluetooth requires password (we know that ... wheellog)

It is theoretically possible that someone with (let say Wheellog app) would connect with default-well-known password to my wheel and change my max speed, that I have limited for my safety. Yes it'd very unlikely gonna happen, especially in the area I live, but still, it's definitely possible.

The newest version of the app might not let you set a password. I downgraded my app to 6.6.2 and upon trying to connect to my V5F it prompted me for a password change.

Thanks for advice @Blank, I did not think they have remove that feature. So I have tried 2 versions I found (6.6.1 and 6.6.5). It indeed allows me to change the "password". BUT ... !!!

But the password for bluetooth protocol still remains 000000, so when pairing with phone using my new password I set, it does not work, but the unchanged default does. Only the old version of inmotion app would require the new pass, which is not a real bluetooth password but something internal to the wheel and app. New inmotion app does not care as well. Wheellong connects as well, cause it simply use hardcoded 000000 pass for bluetooth connection, may mr. @pallachz confirm(?)

Conclusion: Well, info in manual is incorrect/misleading, connection never really was well protected by user defined bluetooth password, but by some parody pass, no wonder they have removed the functionality. Bluetooth pasword is hardcoded 000000 and cannot be changed. Sadly there is still a small chance someone unauthorized person would change V8 settings.
(glad if someone proves me wrong, but I don't think so... :()

My wheel bluetooth stays on and never switch off, so I can't even prevent it by switching it off :( Not very happy about the mix.

One needs to choose a name from the dropbox after typing the "@" (and some first letters) to get a working notification - if it worked out, the name is shown with a blue background: @palachzzz

Inmotion Official App version 7+ automatically resets password to 000000, and you can't use it more. 
So if you want to use password, you need to use official app version 6 to set it.

Thanks @Chriull for adding notification. I know how it's done, but I had to draft my reply in my editor, wait a day and paste it here later, since forum informed me i can only make 2 replies a day (I have not noticed notifications didn't apply and could not fix it.). Thanks again

@palachzzz Are you sure? Maybe v7 reset pasword, but actually I don't think ver 6 sets bluetooth pasword. Yes, the pass to access v6 app changed, but password for pairing was still 000000 accordint to my tests. And it does not matter, because wheellog can access it anyway (whatever secret pass I set in v6, without running v7 to reset it, I have verified that). So there is no reason to use v6, since there is no added security.
