Registering service for iPhone

The iPhone will require eUniStone to use the UUID 0x00000000DECAFADEDECADEAFDECACAFF and
CoD 0x240704 or similar see below. In the below string the above UUID and CoD is used when
registering the service in eUniStone.

AT+JRLS=32,11,00000000DECAFADEDECADEAFDECACAFF,Serial port,01,240704
The eUniStone Class of Device (CoD), set by the AT command AT+JRLS, shall be set to a specific value in
order to be discovered by an Apple device. Using e.g. CoD 0x240704 for the Accessory it will in many
cases not reflect the correct functionality of the device since this means that it is a (Audio, Rendering,
Wearable, Wristwatch) device.
