Overview

Local Exception class.

The @data attribute holds a Hash with informative content. In particular, @data [:reason] holds a Symbol providing the internal error code, currently one of the following:

  • :notype when the packet type code is neither 1 nor 2

  • :nocrc when the CRC16 check fails

  • :noavail when the serialport was not available for reading (timeout)

Typically, the last raw buffer is available in human readable format as:

rescue MmGPSError => e
  puts MmGPS::hexify(e.data[:packet])
end
