![]() ![]() You can exit minicom using the keyboard keys CTRL-A q ENTER. Inserting the module to Raspberry Pi and plug the jumper B, Install minicom. It can also run in the background, even after logging off (Ctrl + A, D. This will connect to the first COM port at 9600 baud and log (option -L) the output to file screenlog.0. UART port and getting data from the desktop on the serial port using Minicom. 2Run the ifconfig command to see if a USB0. We used the GPIO pins for the serial port to contact the Raspberry Pi from. If you only get a blank screen as you type, there is a problem with the UART connection, in which case, try going through the steps in the serial port setup tutorial to check the Raspberry Pi is configured correctly. Waveshare SIM7000E Manual Online: Minicom For Uart Debugging On Raspberry Pi. 49 1 1 2 3 It is easier to use Screen instead of fiddling with configuring Minicom: sudo screen -L /dev/ttyACM0 9600. 1Send the following commands through minicom and wait for the module to restart. If the UART port works, anything you type will be echoed or looped back into the receive buffer and appear on the mincom display. When minicom starts, try typing some characters on your keyboard. The -b parameter sets the baud rate at 115200, and the -D parameter specifies the target UART port as ttyAMA0. Launch minicom with the following command. If you do not have minicom installed, you can install it using apt. ![]() To perform the test, we will use the minicom terminal program. Connecting the RX and TX together will send any data transmitted from the Raspberry Pi through the TX pin back to the receive buffer through the RX pin. If you are using the UART port without any expansion boards attached, you can connect the UART RX (pin 8) and TX (pin 10) pins on the 40-pin GPIO header. On the Serial Pi Plus or Serial Pi Zero, connect the RX and TX pins together, as shown in the image below. You can test if the UART port on your Raspberry Pi works by performing a loopback. ![]()
