GPRS SHIELD v1.0 Test

Products & Technology Shields
#1

Hello, I bought seeedstudio.com/wiki/GPRS_Shield_V1.0 with arduino uno and I tried to use the source code of that link (send2pachube) and give me a +CME ERROR: 3, so i decide to try another source code

/*
  This code is refer to the example of PachubeClientString of Arduino

  Different countries may use different APN name, this example is work in China,
  we use APN name of CMNET, please do not use it in your country.
  
  Circuit:
  * Battery positive port attached to analog in 0
  * Temperature&Humidity sensor attached to analog in 5
  * GPRS Shield attached to digital 7,8

and the serial monitor data here

AT+CSQ

+CSQ: 23,0

OK
AT+CGATT=1

OK
AT+CSTT="internet.ideasclaro"

+CME ERROR: 3
AT+CIICR

+CME ERROR: 3
AT+CIFSR

10.14.65.46
AT+CIPSPRT=1

OK
AT+CIPQSEND=0

OK
AT+CIPSTART="TCP","api.cosm.com","8081"

OK
AT+CIPSEND

+CME ERROR: 3
{"method" : "put","resource" : "/feeds/91687","params" : {},"heAT+CIPCLOSE

+CME ERROR: 3

The error i’m getting crazy because i read about in several forums and shoudn’t be problem, some times after power down and power on several time no givme error, this is very frustrating i hope anybody can help me, thanks in advance.

Hi,

Here is the step by step procedure to troubleshoot your issue

1.Check the APN name.
2.Upload the code.
3.Open the serial monitor(Error will appear).
4.Switch off the GPRS shield(In this state only the Green LED will glow).
5.Switch on the GPRS shield after some time(In this state Green and Red LED’S will glow).
6.Check the serial monitor again(The error would have disappeared now).

Let us know if it works.

Thanks and Regards

Hi , I did the procedure that you indicate but this is the results

AT+CSQ

+CSQ: 22,0

OK
AT+CGATT=1

OK
AT+CSTT="internet.ideasclaro"

OK
AT+CIICR

OK
AT+CIFSR

10.65.50.114
AT+CIPSPRT=1

OK
AT+CIPQSEND=0

OK
AT+CIPSTART="TCP","api.cosm.com","8081"

OK

+PDP: DEACT
AT+CIPSEND

+CME ERROR: 3
{"method" : "put","resource" : "/feeds/91687","params" : {},"heAT+CIPCLOSE

+CME ERROR: 3

Do you have another source which can I try? thanks in advance.
