| GSM M95 Quectel not sending/receiving SMS |
 Posted: Thu May 19, 2022 6:21 am |

Hello,
I have a M95 Quectel module (Clicker board from MikroE).
This one: https://www.mikroe.com/gsm-2-click
And a https://www.mikroe.com/clicker-2-pic18fj where the GSM module is mounted to.
I have used the code from GABRIEL BARRIOS and I have contact with the module.
And it was working...and suddenly it stopped. Now I have changed the SIM card (result is the same) and I think that there is some register I am missing to initialize but I just cannot find it.
So my question is: Is there somebody who has a Init for this module?
To make anything clear I will post my project (or the Init).
But right now I am pulling my hair!!!!!
Best regards,
Jody |

Just some hints...
You need to start with a terminal connected, check what is working:
autobaud AT
simcard with CPIN
Signal CSQ
Reg CREG
Use the datasheet:-)
When you do the code use the STATUS pin to know what state the module is at.
When entering commands use returned "OK" or what the datasheet say must be the end of the commands.
Many just use a delay, but it won't work in the real world. Some commands respond in few ms, and others in many second. |

What version CCS compiler are you using?
Please post the first part of your code up to and including the RS232 initialization lines.

I can communicate with the M95. Read and write to the module is fine.
CREG = 1,1 and sometimes 1,2
I start with a GSM_SMS_init_1() include this function with this post.
Also include the functions called from that init file.
And sorry for the long post
| Code: |
void GSM_SMS_init_1(void)
{
extern int gsm_init_error;
gsm2_reset();
gsm2_module_power();
gsm2_reset();
gsm2_module_init();
if(!gsm_init_error)
{
//**************************************************************************

if(Check_COM())
{
Clear_buffer();
fprintf(RS232,"COMMS ARE GOOD\n");
fprintf(RS232,"MOVING ON...\n");
delay_ms(500);
}
else
{
fprintf(RS232,"COMMS FAILED\n");
delay_ms(500); // Delay a maximum of X seconds;

most of this code is from GABRIEL BARRIOS.

My suggestion...
Maybe for testing it can work, but not in any production.
All the code is based on delay() and no change to know what is going on.
The code doesn't handle CREG right, 1 means reg local net, 5 is ok too, it is reg for roaming. Ex. simcom can be confused and return a 5 where it is a 1. Or you can plug a simcard there must be roaming, 2 is searching....The code is not handling that.
When sending an SMS it can take up to 90 seconds, most is done <6sec, and the module is not ready for new AT commands. In best case it ignores them, worst case they all be processed after it returns from the sending. Therefore code with delay() is no go. From my view you must make a more stable way to deal with all this.
Do a receive buffer and do all your lookup from that.
It is also important to pay attention to the STATUS pin.

Oke have did some testing:
Just connect a USB-? SERIAL to the module.
And can communicate with the module and here is the communication I have done with the module. It seems to be working but it doesn't want to connect to the network.
| Code: |
AT
OK
AT
OK
AT
OK
ATE0
OK
AT+IFC=2,2
OK
AT+CMGF=1
OK
AT+CREG=1
OK
AT+CREG?
+CREG: 1,2
OK
AT+CPIN?
+CPIN: READY
OK
AT+CSQ
+CSQ: 28,0
OK
AT+CREG?
+CREG: 1,2
OK

Module have ok signal, and searching for net (creg 1,2).
When searching for net, it is your provider there have the control, you can ask them why your simcard is not getting connected. If using 2G the module will draw about 2,5Amp for the registering to take place. If power drop module typically reset itself... |
