These remedies apply to the case when you receive some data and you get this warning message:
'Bluetooth' unable to read all requested data
ASCII Data
When using the Bluetooth® interface for:
Reading ASCII (text) data using the fscanf,
fgets, or fgetl functions
these are possible causes and remedies:
| Cause | Solution |
|---|---|
| An incorrect read terminator was used. | Verify that the Terminator property is set to the
value required by your device. For more information about setting the
property, see Terminator. |
| Communication with the device was interrupted. | Check your device connection. |
Binary Data
When using the Bluetooth interface for:
Reading binary data using the fread function
these are possible causes and remedies:
| Cause | Solution |
|---|---|
The number of values to read was not specified and was set to the
InputBufferSize by default, or the number of
values to be read was specified to a value greater than the
BytesAvailable property. | Set the number of values to read using the size
argument on the fread function, or change the
InputBufferSize property. For more information
about setting the property, see InputBufferSize. For
information about setting number of values to read, see fread. |
| Device did not send all the requested data. | Check your device connection. |
| There was a data format mismatch. | Verify that the device data format matches the specified read format.
Data format is set using the Precision property. For
more information about supported precisions, see fread. |
Binblock Data
When using the Bluetooth interface for:
Reading binblock (binary-block) data using the binblockread
function
these are possible causes and remedies:
| Cause | Solution |
|---|---|
| The timeout value might be too short for the amount of data being read. | Increase the Timeout property value. For more
information about setting the property, see Timeout. |
| Communication with the device was interrupted. | Check your device connection. |
