Bluetooth no pairing after update

[ravanzaanen]

Hi Guys,

I have this strange problem. I use a few heart rate sensors and after the update to android 10 this weekend 1 of the sensors won't connect to the bluetooth. But another sensor i got in this week from same brand does connect.

No i know normally you can say forget and reconnect. But that option i don't have at the moment. The pairing in the software keeps spinning while the new sensor is connecting in seconds. 

How can i let my phone forget about this 1 bluetooth connection mac adress because it is something only with this device. 
I already reset the device to factory defailt but that did not work. I think it is something on the phone.
Hope somebody can help me out because with 2 sensors one working and one not is very annoying.

This is what i did and what i did wrong first times.
Turn off bluetooth
Go to settings-> apps
Turn on system apps
look for bluetooth
Clear bluetoothtest cache and data
clear bluetooth cache and data
Turn on bluetooth again.

the times before i did not turn of bluetooth and that did not work.
