Copernicus GPS Receiver 113
FIRMWARE UPGRADE 11
Packet ID – 0x86 (Change Baud Rate)
This packet forces the target system to change the serial baud rate to the specified
rate. The valid baud rate values are listed in the table below. The target system returns
ACK in the old baud rate before the change and another ACK in the new baud rate if
the change succeeds. If the baud rate change fails, the unit returns NAK in the old
baud rate.
Packet ID – 0x8F (Erase Firmware Section)
This packet initiates the erase operation on the target. It only erases the firmware
portion of the Flash chip. The target returns either ACK or NAK indicating the result
of the operation.
