NINA-B306 Range Limitations and Optimization

Due to the design limitations of this board along with the PCB antenna on the NINA-B306, the range of the radio is quite limited with a max range of 20-25 feet.

Users struggling with getting this range should increase the power of the antenna with the Bluefruit.setTxPower(8) command. The 8 value in this command references the power in dBm. Refer to the Bluefruit52 library for valid values for this command.
