(Table no. 1)
Note*:
Set up and collection of the optical port communication frame is as follows:
•
Baud rate, Number of Bit, Parity, Stop bit
The values for each parameter are as follows:
•
Baud rate: 300, 1200, 2400, 4800, 9600, 19200
•
Number of Bit: 7, 8
•
Parity: N (none), E (even), O (odd)
According to the above description, if we want to connect with the meter with baud rate: 4800
and number of bits: eight and parity: E with the last 1 bit, the command format will be as
follows:
➢
AT+AD Frame =4800,8,N,1<CR><LF>
Note*:
Generally, for meters that comply with IEC 62056-21 standard, the command should be:
➢
AT+AD Frame =300,7,E,1<CR><LF>
Note*:
In case any command other than the mentioned commands are sent to the optical probe,
“Invalid Command!” will be returned and if parameters are not set correct, “Invalid Parameters!”
will be returned.
Upgrading Firmware
The firmware can be upgraded in two ways:
•
Send the file through the windows-based application
•
Send the file through any program via Bluetooth that can send commands
