I'm not able to connect when my device is more than 6 feet away. I have a DA14586 with a ZOR Antenna 1.6mm substrate (design from 5.4 AN-B-027). It has a matching circuit that AN-B-027 recommends which I've uploaded (Antenna_cir.pdf). I think I should be getting more range. Is there something else I should be doing?
I'm using some Bluetooth debugging software and I get -85dBm at 6 feet.
Am I supposed to put a setting in OTP_HDR_TRIM_RFIO_CAP_ADDR to help the DA14586 match the antenna/network?
