Error code 0x0F (general error), is generated when BlueMatik responds with an error message but specifies
no error number.
understood. Error code 0x0F can also be generated (i) on disconnection if both sides attempt to initiate the
disconnection, or (ii) if data is sent before a connection was established or after it was closed (since BlueMatik
will try to interpret this data as a command). Note in particular that if a remote device disconnects while
ToothPIC is trying to send it data, a general error be generated. The correct response to this is to perform a
BMTC_Reset command to return BlueMatik to a known state. See any of the firmware solutions for an
example of how this is done.
BlueMatik Serial Communications
NOTE: As of ToothPIC 3.0.00005, the transmit buffer is not used and BMTTransmit will not return until the
data has been transmitted.
BlueMatik serial communications services allow you to send data to and receive data from Bluetooth devices
that BlueMatik is connected to. These services are not compatible with the FlexiPanel User Interface services
– you can use one or the other, but not both at the same time.
ToothPIC implements buffered I/O with fixed buffers of 256 bytes.
ToothPIC employs the buffers as circular buffers and the following variables and macros are defined in
ToothPIC.h:
To read and write data, the following macros and services are provided:
BMTTransmit
NOTE: As of ToothPIC 3.0.00005, BMTTransmit does not use the transmit buffer and it will not return until
the data has been transmitted.
The BMTTransmit service transmits serial data.
