lk3_uart.png
Pin 1(UART_TX) on IDC10-1 should be 3,3V, this pin must be connected to uart_rx pin from simm900
upgrate Lk3 to this software lk3_firmware_1_39b1.bin.tar.gz
In LK3 menu "uart devices" you have to choose GSM SIM800L
Hello, yes it works now, but I had found out that in one of my LK3 the uart port is somehow burned (possibly due to the previous experiments with SDS011 sensor).
Also, this SIM modem was configured to 9600 baud by default, and the LK3 communicates using 115200, so they could not establish communication. I had to manually change the baud rate on the SIM modem. The old firmware works also!
Thanks for all the help!
Also, any news on the implementation of the OLED I2C LCD?
