IOS 26.3 Bluetooth probleem

Hallo, ik heb problemen met mijn iPhone 13 IOS 26.3 : Mijn telefoon maakt de Bluetooth-verbinding niet met mijn E-Bike (Bosch Kiox 300) IOS-versie vóór 26.3 was in orde. Na update naar 26.3.1 dezelfde fout.

Als ik de iPhone Pro 14 gebruik met 26.0.1 werkt alles ok.

Dus ik denk dat er een bug is in de nieuwste IOS-versie?

Help alsjeblieft.


Bedankt

iPhone 13, iOS 26

The "help" from Bosch Ebike center didn't help, but the problem is solved (YouTube tips):


Iphone: Privacy and Security. /. Bluetooth / Delete the connections

Iphone: Regular / transfer or reset iPhone / Reset / Restore Networksettings

Make new bluetoothconnections with the devices.


Thanks everyone

Frank ~ Your iPhone 13 could be 4½ years old and the long process of applying a major iOS upgrade to an iPhone with a weak, aging battery can be the proverbial "straw that broke the camel's back." (A weak battery often manifesting as connectivity issues.) So...


Does your iPhone 13 still have its original battery?


And what's the Maximum Capacity % here?...

Today , I have received an answer from Bosch Ebike service center. :

1.Verwijder de eBike uit de Flow App

2.Verwijder de "smart system eBike" uit de Bluetooth-instellingen van de smartphone

3.Verwijder de Flow app van de smartphone

4.Start smartphone & eBike opnieuw op ***BELANGRIJK***

5.Installeer de Flow-app en login met je corecte accoiunt gegevens.

6.Probeer een nieuwe koppeling 


The steps 2 -6 I did several times without success. No one told me to do step 1 first (Remove te Ebike out the Bosch-Flow-app). So tonight I *** step 1-6. In a few days I will report here the results !!

That was the first thing I did: Bluetooth:Forget Device Bosch Flow / remove Bosch Flow App / iPhone out and ON again. Install the flow app and a new bluetooth-connection with the Ebike. No results. Also I removed all the other bluetooth-connections. Earphone/Garmin Bike/Garmin Car/Selfie stick/etc. No results. (all the other bluetooth connections works perfect). I have sent an @mail to Bosch. I hope an answer after this weekend. Do you think a total reset and (factory restore) could help ? Tomorrow someone would help me with an Iphone11 with iOS 26.3.1 to test the above mentioned problem. (apologize for English language errors. I'm 70+ years old from the Netherlands)

IOS 26.3 Bluetooth problem


Hello, I am having problems with my iPhone 13 IOS 26.3 : My phone does not connect the Bluetooth with my E-Bike (Bosch Kiox 300) IOS version before 26.3 was fine. After updating to 26.3.1 the same error. If I use the iPhone Pro 14 with 26.0.1 everything works ok. So I guess there is a bug in the latest IOS version? Please help.

Frank ~ 89% is surprisingly high for the original battery in that old model iPhone. So let's do one more check... Go to:


Settings > General > About


...Do you see a 'Parts & Service' section there?


If so, tap it and in the resulting pane, does it say anything about the battery and it being 'Genuine' or 'Unknown'?
