For now, here a my two test programs with 16F690 and 18F1220.

Surprisingly (to me), both accept the STR length as variable in the 3 ways I'm using it (HSEROUT, SEROUT2 and DEBUG).

I'll go back...

Yup, I will do so asap.... Sorry, didn't have much time yesterday.

Well, I'll give it a try with a 18F1220 when I'm back home tonight.

It's the one I always use: 16F690.

Thanks Henrik,

I went this way already but so it is correct, the number of characters cannot be replaced by a variable.

Strange....

Hi there,

I'm using HSEROUT with the STR modifier and I can't find the way to set the number of characters "\n" in a variable instead.

While this works:

HSEROUT [STR BalBuffer\40,26,13]
...

Hi All,

Yup....initilisation....

I declared an array:

...
RxBuffer VAR BYTE(18)
...

No, I actually never use CLEAR.

BTW,

In the AT command book for my module (SIM7600E), I finally noticed this:

9021

There is no mention of this ESCape command in the datasheet, just here in this table. But, unlike it is...

Thanks Pedja,

Where I live, 2G has been by end 2020 so I choose to go SIM7600E.

And thank you for all your usefull remarks :wink:

Pedja,

May I kindly ask you what type of modem(s) you use?

Hi Richard,

I actually never saw this "+++" command - I'll give it a try asap :wink:


Pedja,

I'm thinking of doing the same thing, repeating commands and waiting for acknowledgement.

As...

Hi there,

I was wondering if there is any way to get out of a "sitting" situation from a GSM module when, i.e., a AT+CMGS is misissued.

This situation I'll discribe further on should actually...

Hi all,

I'm struggeling for hours trying to find out why my program is working or not working depending on where I place the variables initialisation in my program. It's about to send an SMS and...

Thank you pedja,

I'll give it a try with what I have in my drawer up to now.

I still don't know what MOSFET I should choose....

Thanks pedja,

The schemas come from this exact document you refer to in your last post, adapted to DC supply.



Can you please explain?

Without any "switch" (MOSFET in this cas, how I...

BTW, I don't think the above schema will work.

Is this really correct?
9014



Shouldn't it be something more like this?
9015

Hi All,

I'm now (finally...) building my project and its about time to order the missing components to have something to play with (without any reference to naughty thoughts :D).

So, here's the...

Hi Henrik,

Obviously, the beam was far too big for my little eye! :D

Thanks a lot :wink:

Hi All,

As HSERIN and HSEROUT are working well on my 18F1220, I can't make DEBUGIN work (DEBUG is okay).

I couldn't find any information searching in the forum and googeling around so if...

Thanks pedja089, I'll give it a try the way you suggest :smile:

Well, the AT+CMGL="ALL",1 doesn't exist (at least not for the SIM7600E module).

What it's datsheet says:
9005

Okay, this is new to me.

I'll give it a try right now - thanks a lot :wink:

Hi pedja089,


I think, that's where I'm currently stuck - I have no idea how to achieve this (appart from using command AT+CMGR=n but this implies I have listed/sored the message's index before),...

Hi all,

I'm banging my head playing around with AT commands to find a way to list received SMS messages without changing their status (REC READ, REC UNREAD, etc).

AS a matter of fact, if my GSM...
