I was running a test application on my CYW920719Q40EVB-01 Evaluation Kit and looking at it with a BLE monitoring app. When I plugged in an antenna, it didn't seem to increase the RSSI according to the app. It looks to me like there's a resistor or capacitor missing on the connection which routes it to the PCB antenna instead of the external antenna. I bought this specifically because it had an external antenna option, but is it not actually connected?!

To use external Antenna, C67 needs to be moved from position B-C to A-C.
