Hi All,
Is anyone facing similar issue?
Here is story:
I'm using BTM571 (QCC5171) module in my design and testing TWS set of two modules connecting to different smartphones.
The firmware is running pretty standard (earbud project) from SDK almost w/o modification.
The TWS set works just fine with Pixel 4a and existing antenna implementation (Taoglas FXP75)- see HW details shown below.
The range is about 20 meters radius from Pixel 4a which is sufficient for me.
The same TWS set and antenna works just worse with iPhone 12.
Highly difficult pair and connect on short distance. While connected it works only at distance 3-4 feet and iPhone is breaking connection.
I changed antenna on to much more bigger (FXP74). It helps a bit, but "connectivity problem ratio" is still the same.
Working excellent with Pixel 4a at long distance (30-40 meters), while iPhone connectivity breaks at 10 meters and have pairing and connecting issue at any distance.
Both audio codecs works - AptX for Pixel 4a and AAC for iPhone.
I'm suspecting something is wrong with Bluetooth RF configuration or BT pairing protocol needs to be adjusted specifically for iOS?
Is any specific .htf config settings related radio?
Appreciated for the help!
