Ussd query issues #104

Closed spidy0x0 closed 2 years ago

spidy0x0 commented 2 years ago

hi, i am trying to make a simple ussd query to check balance and i have been struggling for hours. My brain hurts. this is my code

let serialportgsm = require('serialport-gsm')
const ussd = require('./node_modules/serialport-gsm/lib/functions/ussd.js');
let modem = serialportgsm.Modem();
ussd(modem);

let options = {
    baudRate: 115200,
    dataBits: 8,
    stopBits: 1,
    parity: 'none',
    rtscts: false,
    xon: false,
    xoff: false,
    xany: false,
    autoDeleteOnReceive: true,
    enableConcatenation: true,
    incomingCallIndication: true,
    incomingSMSIndication: true,
    pin: '',
    customInitCommand: '',
    cnmiCommand: 'AT+CNMI=2,1,0,2,1',
    logger: console
}

modem.open('/dev/ttyUSB0', options);

modem.on('open', () => {

    console.log(`Modem Sucessfully Opened`);

    modem.initializeModem(() => {

        modem.on('onNewIncomingUSSD', (data) => {
            console.log('onNewIncomingUSSD', {
                data
            });
        })

        async function main() {

            await modem.setModemMode(msg => {console.log('set pdu msg:', msg)}, 'PDU');

            let command = '*124#';
            try {
                let r = await modem.sendUSSD(command);
                console.log(r);
            } catch (err) {
                console.error(err);
                // handle the error here
            }
        }
        main();

    });

})

after running it,this is the output i get

is there anything i am doing wrong? Please help

after the changing the command to 7-bit

*124# --> 2A31323423

i get this output

i am not getting the balance message

spidy0x0 commented 2 years ago

After days of intense suffering, i found the solution.

first run this : AT+CSCS="IRA"

goto http://www.rednaxela.net/pdu.php

alphabet size: 7

enter USSD code (eg. *124#) , click convert

in the 2nd box, copy the third line

add it to your ussd section: AT+CUSD=1,"AA988C3602", 15

after getting the output in 7bit (CUSD=1,"xxxxxxxxxx..7bit"), copy it

goto http://smstools3.kekekasvi.com/topic.php?id=288

in the "USSD Entry/Display" section, select GSM 7bit packed

paste the result you had from the modem

click convert

after the changing the command to 7-bit *124# --> 2A31323423

the issue here is, i was using the 8-bit alphabet conversion. 7-bit solved the issue

to do this programmatically, use https://www.npmjs.com/package/ussd-pdu-text-converter
