After [upgrading the radio module firmware](https://forum.arduino.cc/t/radio-module-firmware-version-0-2-0-is-now-available/1147361/11) and [installing the Beta version of the ArduinoBLE library](https://forum.arduino.cc/t/radio-module-firmware-version-0-2-0-is-now-available/1147361#b-install-beta-tester-version-of-arduinoble-library-7), I installed the HardwareBLESerial library and ran the SerialPassthrough example. I then opened up the Adafruit Bluefruie Connect app on my iPhone, and voila, bidirectional communication.

I am one happy camper. Thanks to the Arduino team!
