Everyone,

I am struggling with my Waveshare GSM-Module to establish M2M communication (http://www.waveshare.com/wiki/GSM/GPRS/GPSShield%28B%29).

There're two serial ports on this device. The GSM-Shield itself and some separate connections for the SIM808 to connect directly to it. However I could not get it to work. Even on Arduino.

Has anyone done this before? Does anyone use this module?

kind regards,
Alex

Have you found the UART selection switch?

I'd make sure it's on USB, open a terminal app on your PC, and make sure you can communicate with the SIM808 directly... Then switch it over and try and do the same from the Espruino...

It could just be that the switch is in the wrong location though?

Sorry, I have forgotten to reply. I switched to the SIM900 lately and did not go anyfurther. I will take your recommendations into account. kind regards, Alex

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
