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?

Hi, 

you have tested with multiple other phones and it works for them? 

The crystals you use on your design, what is the CL, load capacitance and what is the values on the load capacitors? Both for 32.768 kHz and 32 MHz.

Best regards,
