BMTRxWaitBytes
The BMTRxWaitBytes(i) macro waits until there are i characters in the receive buffer. It can be called
before BMTRxAdvance to avoid buffer underrun. . i must be of type unsigned char – this is a macro and no
type casting is done.
Bluetooth Device Classes
The 3-byte Bluetooth device class, specified in the ToothPIC Settings and Link Key Map as the variable
DeviceClass, determines what the module claims to be when other Bluetooth devices ask it. It affects the
icon that appears on other Bluetooth devices and may affect the device discovery function. In particular some
mobile phones only look for certain sub classes, e.g. headsets.
The device class consists of three elements: the services available, the major device class and the minor
device class. BlueMatik can be programmed to claim to be capable of any number of services, however
exactly one Major Class must be specified. The minor device class is an optional addition, defining a subset
of the major device class.
Services and Major Device Class
The first two bytes of the device class contain the services information and the major device class. They are
calculated by bitwise-ORing together as many services that are required and the one Major Device Class
required. (ToothPIC.h provides definitions for these values.)
Example
If BlueMatik is required to claim network and object transfer and information services, and appear as a
peripheral then the device configuration bytes are:
