Accu Chek wireless adapter red light flashing on failed data transfer to iPhone 12 mini.  
The “mysuger” app and my Accu Check Mobile wireless adapter (recently fitted) did work for a few days. Now, the data transfer starts with the green flashing light working. After a short time the green flashing light turns a red flashing light, the data is not transferred.  
I have searched the web and Cannot find any reference to the significance of the flashing red lightred light.

Assuming it is Bluetooth transfer. Did you try unpair and repair?
