If there's a usb connection, it probably shows up as /dev/ttyUSBx or /dev/ttyACMx

Otherwise, there's probably TX/RX pins for connecting a serial - could use the gpio pins, or get a cheap USB to TTL serial convertor. Need to take care to match the voltage levels.

i applied this procedure https://alselectro.wordpress.com/2018/0 ... -with-gsm/ but when i write

Code: Select all

picocom –baud 9600 /dev/ttyS0
i got terminal ready but still i can't type any thing i searched this problem i found many answers all the answers tells the problem is in connection ? and my connection is true because very simple two wire's RX to TX(sim808) and put diode forward in middle with resistor 10k and TX to RX directly but i thinking if any method to know if connection true inside command ?
thanks for response
