How do you know it's disabled after booting? Do you see the i2c devices with ls /dev/i2c* immediately after booting? I have a program display on 16x2 LCD, I make it run every boot, and LCD is blank because the program cannot find the port I2C, after I enable I2C with raspi-config, the program worki...

Hi everyone, I enable my I2C port by sudo raspi-config and everything running good, but after reboot, it go to disable again, I check raspi-blacklist.conf It dont't have any thing like blacklist i2c-bcm2708, I go to /etc/modules it have i2c-dev, i2c-bcm2708, I go to /boot/config.txt It have dtparam...

You need to decode it from 7-bit GSM USSD to 8-bit ASCII. It will then print without any errors.

But how come I decode it when the orginal 7-bit GSM USSD data is corrupted already

Repeating your original question doesn't seem very productive... What do you expect the returned data to say? What values or quantities are represented by the <?> placeholder symbols? oh no, this situation is like that, I try to get the response of the serial, this is the full respone: +CUSD: 1, "D...

It's returning 7-bit data. You need to convert that to 8-bit to make sense of it.

Can you suggest me how to do that or the key word to find the solution ?

Hi everyone, I am coding the python script for check balance of the sim on module GSM A6, here is my python code: port = serial.Serial("/dev/ttyAMA0",baudrate=9600,timeout=1) port.write('AT+CMGF=0'+'\r\n') time.sleep(2) port.write('AT+CSCS="HEX"'+'\r\n') time.sleep(2) port.write('AT+CUSD=1,"*101#",1...

Oh thank u so much I try to convert with USSD Entry/Display and I got the data I need, thank u so much
