Hi Viktor

If I use a keyboard then things work as you document, but if I create a Macro which has my message and termination character, I need to use the SUB character (Hex 1A). I suspect if I use Flowcode to create predefined messages then I would need to use 1A as termination.

I haven't tested this though.

Hi.
Did you use Putty and all worked?
You can get a sms to your mobile phone?
No problems?

Hi Viktor

I'm not using PuTTY but another Terminal program. Using it I can get the module to dial out and it can send and receive SMS messages. The only issue is that I need to use Hex 1A to terminate the message string, which contradicts documentation.

I now have it communicating with ThingSpeak but there is a problem with what I'm sending as the server returns 400 or 406. Probably something silly I've overlooked (I hope).

OK

[viktor_au]

Understood. Thank you. What terminal do you use?

Hi

Usually I use "Terminal by Br@dy" as it allows me to create Macros so I just need to press a button to send a string of characters. On another machine I have a few programs including PuTTY, so maybe I'll try with them.

Thanks.
Would be great for people, who follow this project if you can share the code on Terminal v1.9b by Br@y++.
Can you share?

Hi Viktor

For making the call and sending SMS messages I have already.

I have now found some documentation on a Google search that does actually refer to Hex 1A to terminate, calling it ctrl+z / esc, but my ascii chart refers to it as Sub with Hex 1B as Esc.

I have only had to use that when terminating the actual message when sending a SMS and I am over the USB-USB connection. Not ruling out that being a contributing factor either.

I will use the Tx/Rx pins when I get a chance, for comparison.

Hi
I am a bit lost.
Are you working now in FC10?
