I am connection Water Linked Modem-M64 to the serial port through a USB-to-Serial-UART/RS485 Adaptor. I am connecting Rx/Tx to the port and am using an external power suply to give 12V to the modem. I am using wl-95046 Python library. But, I get this error: Timeout/error connecting to modem. Any suggestions please?
Check that you have connected all wires correctly and that you are using the correct serial port.
A good way of checking if you are able to communicate with the modem is to connect via a serial terminal like PuTYY (More info here). Use baud rate 115200. Once connected you can type “wcv” + Enter and you should get a response from the modem if everything is working correctly. Then you can retry using with the Python library.
