SIM800C AT commands error
Ordered a SIM800C usb device with antenna from AliExpress a week ago. I started trying it out using PuTTY and it doesn’t seem to work like it should. It displays the word “Error” but no details are provided. I’m sure the sim card I’m using has credits and used it to send a couple of test messages through a usb modem. Has anyone experienced this before? Or did I just skip a step? No instructions came with the package so I’m not so sure about what to do.
