iPhone and Samsung connection issues

[ccrider]

We are experiencing connection issues for specific Android & iPhone but not for others (i.e. Samsung Galaxy S9).

Phones with issues

Android Details

• Samsung Galaxy A72
• Android OS Version 12
• nRF Connect App Version 4.26.0 (Latest)

 

iOS Details:

• iPhone 8
• iOS 16.0.2
• nRF Connect App Version 2.5.3 (Latest)\

Would this be a compatibility issue?

Are you asking in relation to the phones that have an issue or the Nordic device being used?

The nordic device

We are using a FWM7BLZ20 Wireless module.  So, we can't  change the load capacitance and don't know the values at this time.   Is there a way  to adjust FW wise to make it compatible with most/all smart phones?
