Introduction
Serial Port Profile (SPP) defines how to pass through data from virtual serial ports to peer Bluetooth Low Energy (Bluetooth LE) devices by adopting Bluetooth LE technology.
Bluetooth Special Interest Group (Bluetooth SIG) does not define standard profiles for Bluetooth LE serial port pass-through. Therefore, to make Goodix-customized SPP user-friendly, this document introduces how to use and verify the Goodix SPP example in the GR5xx Software Development Kit (SDK).
