  1. Hello Dost, I’d like to ask you an advice on a SIM800C module. The CIPGSMLOC command gives me a well defined position (even too defined since it’s stable at the 6th decimal number), almost 1000Km far away from where I’m transmitting. In the examples I found over the net I see always position around Paris, like the one I get (+CIPGSMLOC: 0,2.333626,48.802647,2016/07/29,10:52:14). The version revision is 1418B02SIM800C32_BT_EAT_115200. Even more, I’m getting almost the same position with a Sim928A (CIPGSMLOC: 0,2.326602,48.803823,2016/07/29,10:13:12 , firmware revision 1137B01SIM928A64_ST_ENHANCE). Need FW update? Thank you Reply
  2. I have used SIM 900A GSM Module , I connect GSM module with my pc and verify all l AT command working fine check on PC Hyperteminal. Now I have insert Vodafone sim card in SIM900 device. I send ATD commad to SIM900 module and it call to relative netowork. after 60 second some response like “NO ANSWER” or “NO CARRIER” or “BUSY” get on Hypertemianl. can i change that response using AT command? if yes thensuggest us. I need below response for my application in any network GSM Modem dial call to user then 1) if User Pick call then respnse should be “CONNECT” 2) if User disconnect call then response should be “BUSY” 3) if User not pick call then response should be “NO ANSWER” 4) if user mobile phone in switchoff mode or airplan mode then response should be “NO CARRIER” Reply
    • If you need to know if the user picked the call You should set AT+MORING=1 This will let you know if the other side is ringing or call is answered. If the user Hangs the call you get BUSY by default. may be your provider is not sending the busy code. Try with another simcard. Reply
  3. When SIM900 GSM module dial call to user then if User Disconnect call or Not Pick call or Switchoff mode then SIM 900 display “NO ANSWER” response. SIM 900 Module not give response accroding to condition. so my application not get exact idea user pick call or disconenct call or switchoff mode. Note : Right now i have insert Vodafone SIM card into SIM900 GSM Module and USER mobile Service provider is Reliance and Telenor. Reply
  4. Hello Dost I have flashed my sim900 shield with rev.1137B08SIM900M64_ST_DTMF_JD_MMS DTMF tones are working now but I cannot pass the parameters to set the tone duration. Setting the AT+VTD command has no effect, tone duration is always the same, When I pass the duration parameter to AT+VTS I get error back. In sim900 manual 1.1 there is a parameter for duration AT+VTS=? +VTS: (0-9,*,#,A,B,C,D),,(1-255) OK when I try AT+VTS=”1″ I hear the tone at the remote. when I try AT+VTS=1″,100 AT+VTS=”1″,,100 I get ERROR Having the same problem with AT+CLDTMF command, duration cannot be set. I need to build up a contact-ID protocol time line but without setting the tone duration it is impossible. A I using the correct firmware? Any help is appreciated. Reply
  5. Hi, I have flashed several S2-1040V units (sim 900A) but got a shipment of 3 new ones, didnt look so closly so flashed them all 3 as usual… But now they wount boot. They where S2-1040W-Z1K10 (I think its the W that is the diffrence). Anyone have a working firmwire for them? I have tried to flash everything from this site…. Nothing works. The board just sits and rebots itself every second. (same wire with a 1040V works). /KG Reply
  6. Hello: I have been working with a SIM800 module without problems, but few days ago I started getting the “SIM not inserted” error when I try the AT+CGATT? and I can’t get rid of it… I tried two different modules and 2 different SIM cards and I always get same error….It’s very strange… Firmware running is SIM800 R13.0 I would appreciate any help or comment….

  16. Hello Dost. I am not able to get BT working on my SIM800 module. When I query AT+GSV I get following response: SIMCOM_Ltd. SMCOM_SM800 Rev: 1308B02SIM800M64_BT This possibly means that BT firmware is loaded? If not, which file can I use from your firmware collection? Can you please advise how I can get BT to work? All BT related AT commands give “ERROR”. Thanks Reply
      • I tried AT+BTSTATUS=? and AT+BTPOWER=1 but in both cases I get ERROR as the response. My SIM800 module is made in India and is standard with PWR and RESET buttons, RING and PWR LEDs, etc. Basically I cannot get the bluetooth enabled. GSM works very well. I am using a small 12 V DC power adapter giving about 500mA. Please help. Reply
  17. Hi Dost Muhammad: I work for an Utility in Costa Rica. We have a GSM Shield for Arduino, It has an SIM900 chip, and it’s firmware is 1137B15SIM900M64ST. In the web page of SIMCOMM2M, the SIM900 supports FOTA feature, but I was wondering if it’s necesary to change the Firmware to enable the FOTA feature. I saw in your webpage the firmware 1137B01SIM900M64 ST DTMF JD MMS FOTA. Best regards. Luis. Reply

So i updated the latest firmware as 1137B03SIM900A64_ST_ENHANCE. And flashed it successfully I CANNOT SET BAUD RATE BACK USED AT\r command no respone any help? Reply
      • SIR IT WORKED FOR WHEN I REFLASHED WITH 1137B03SIM900A32_ST BUT SAME AT+DDTE=1 ERORR REPLY FIRMWARE FOR FLASH SIM900A TO USE DTMF COMMAND Reply
        • what is the difference between 1137B03SIM900A32_ST and 1137B03SIM900A64_ST_ENHANCE 64 st is nnot working on my sim900a Reply
          • 1137B03SIM900A32_ST is for Sim900A with 32MB of Flash 1137B03SIM900A64_ST_ENHANCE is for SIM900A with 64MB of Flash
          • The problem here is you have a 32M version of Sim900A for which the new firmwares are not available.
  19. Hi! I have a sim800 module and am trying to use its bluetooth capabilities. But any such bluetooth commands like “AT+BTHOST=?” is giving me an error response, so I’m assuming the firmware that’s preloaded doesn’t support bluetooth functionality. I have come across 1308B08SIM800M32 firmware, but how do I load this firmware?Any tool that may aid me in uploading the firmware? Reply
  20. I have a SIM800L that will not provide any response to AT commands. I know the SIM800L is getting the commands via viewing signals on an oscilloscope on the unit’s RX pin (also the unit will shut down when sending a “AT+CPOWD=1” command. On the TX pin, nothing is ever transmitted back. Is there something wrong with this chip or has the software become corrupted? Reply
        • I downloaded the SimCom SIM800H EAT flash tool (since I didn’t see a flash tool for the Sim800L)… I unzipped the files and ran the “SIMCOM_SIM800H_EAT_flash_Tool.exe. I changed the comm port to the appropriate comm and then loaded the .CFG file associated with the SIM800L (1308B09SIM800L15.cfg)… the program than showed four files “ARM_BL”, “ARM_EXT_BL”, “PRIMARY_MAUI”, “VIVA”. Not having any instruction, I checked them all and clicked “Download”. The flash tool does nothing… just sits there at 0% (no files loaded to my SIM). Do you have any ideas as to what I’m doing wrong?… again, are you aware of any instructions on how to use this tool? Any help would be greatly appreciated. 🙂 Reply

  26. I am currently working on SIM7100E. I am unable to initialize it. I can not sent the AT commands to it. Can you please help me with the initialization of the module? Thanks Reply
      • I got through that. Thanks. But now the problem is that i do not know how to register to the network and in what sequence is should apply the commands to use it for GPRS and 4G. Please help me with that. Thanks Reply
          • The application notes are not much detailed. They have just grouped together the commands in any random order and compiled them into application notes. So I am unable to take any help from them.
