Firmware update

AT** starts the update process for the firmware (flash update).

After AT** is entered, the device prepares itself for receiving the new firm-

ware.

After the response „Send .HEX file now.“ the firmware (file with the

extension HEX) is sent as a text file in ASCII mode.

To update the firmware, hardware handshake (RTS/CTS) must be activated

at the terminal.

After the file has been sent, the firmware update needs some (up to 60) sec-

onds time during which the update is carried out.

After the flash update, the device is completely reset.
