Solution
Check the following:
Make sure the command is supported in the currently running program.
Check the documentation for the opCode the host sent and make sure it is correct and
supported.
Check the previous module responses for an assert (0x7F0X) which will reset the
module into the bootloader.
FAULT_UNIMPLEMENTED_OPCODE – 102h
Cause
Some of the reserved commands might return this error code.
This does not mean that they always will do this since ThingMagic reserves the right to
modify those commands at anytime.
Solution
Check the documentation for the opCode the host sent to the reader and make sure it is
supported.
FAULT_MSG_POWER_TOO_HIGH – 103h
Cause
A message was sent to set the read or write power to a level that is higher than the
current HW supports.
Solution
Check the HW specifications for the supported powers and insure that the level is not
exceeded.
The M5e 1 Watt units support power from 5 dBm to 30 dBm.
The M5e-Compact units support power from 10 dBm to 23 dBm.
