LK3-NOWY SOFT - KOLEJNE WERSJE

[ghorvat]

Hi, what is the procedure for connecting the SIM800 modem? I have connected the modem but there is no response? When I click on "Send if you have connected.." nothing happens on the UART port? Also, when I click the Send Command button, also nothing happens on UART port? I measured the signal with the oscilloscope and the UART_TX pin on the LK3 in constantly at GND (0V).
