Hi ravi, I have a sim800h module fitted with msp430f5232 mcu I want to change APN setting in sim800h there is no pin for rx,tx in sim800h rx,tx directtly connected to msp430. Its a luminous solar pcu module that is use for sending data to server. Please guide me on this. Thanks in advance
Hi, You can set apn using mcu code right?. If it's a pre-designed hardware, Normally a interface is provided for setting apn. May be by uart. Is this hardware designed by you or others? . If others, best way would be to refer manual or ask them. Don't forget to share and subscribe :)

Can I upgrade sim800a with sim800c firmware because sim800a firmware not uploaded on Simcom.ee and sim800a and sim800c has almost same features like Bluetooth
Good Evening! This tutorial seems very helpful. I have tried flashing the SIM800C module using UART and it works fine. But when I try with USB it doesn't. Should we install any supporting drives to flashing using USB? Can you plz update on this. Thank you.
Thanks for the wonderful tutorial which made my work simple. Is that mandatory to switch ON the module after clicking download. Is it possible to download when the power is ON. Else it has been mentioned in any release document. Please clarify me regarding this.
Hi, thank you for the tutorial. I have been working with SIM800L module. But i couldn't get the firmware for sim800L. Could you plz share the file link if you have any? Thank you.
hi.. i want to know that what is the use of GPIO lines on SIM800 is there any possibility to program them as similar to a micro controller to interface extra peripherals like sensors and relays
It's difficult to say but the B09 was higher version to B05 in SIM900. And last digits indicate whether its for 16MB FLASH OR 24 MB or 32MB Flash memory device

Hi Oleg, Yes, they will need different firmware versions each. Its better to contact the local SIMCOM support team for firmwares. They will be able to help better .

I have a problem with connection to the gsm network with the module sim800L previously worked perfectly, but a few weeks later I no longer connected to the network, now the LED flashes 7 times and does not receive a signal, can I solve the problem by updating the firmware? thank you friend for your help
Hi, If it flashes 7 times and stops and restarts flashing then its restarting due to undercurrent. Check your power source. Please post tech queries to embeddedadvice.com with relevant details . We can discuss. Dont forget to Subscribe :)
Thanks Ravi for the greate video. I want to know if I can download my own firmware (I have developed)? or the upgrading with fixed firmware by SimCom? Thanks
Hi, Thanks for watching :) This method shows you to upload SIMCOM stock firmware. The SIM800 modules support our own code to be written and programmed in them, But its not officially supported by SIMCOM and hence very less documentation available.
No :) You can only use the AT command given by them. Only difference is you wont be needing a extra MCU. Thats all. Your code will run on top of their firmware as a process running AT commands. Search for Embedded AT commands.
The procedure is same for SIM800L as well. Just get the right firmware and flash as shown in video. Have any problems , post here. www.embeddedadvice.com/ We can discuss. Dont forget to share and Subscribe :)
Ravi Pujar ,I have USB to UART but it does not write either as I connect it with RX,TX,GND pins that I soldered on to it and try to transfer the firmware but nothing happens and if I try to power on the device error comes cannot communicate with device,am I doing something wrong?
Bhavin, Its not straight forward connection. You need to use IO level translators if your GSM module board doesnt have it. SIM900 /SIM800 modules are having max IO voltage level of 2.8V. Normally USB-UART TX ,RX IO lines are at 3.3V or 5V so you cannot connect directly. If you do, it will damage the module IO ports. Check module baud rates after this is fulfilled.
hallo ravi,,, i have a problem with my SIM800L... DA error in my download progress... error: S_DL_MAUI_FLASH_ID_NOT_MATCHED_WITH_TARGET(5095) can you help me... thanks..

There are two types of firmwares 32bit and 64 bit. You need to use right firmware by checking the current firmware on your device. You can drop mail to SIMCOM support, they will help you sort it out by looking at module serial number.
Meu sim800L não salva comandos de configuração. Por exemplo, eu envio AT+IPR=9600. Logo após eu verifico com AT+IPR? e ele retorna '0', ou seja, auto baud rate. Pode me ajudar?
Ravi Pujar thanks for your attention. I fixed the problem in my case. I just waited about 7 seconds for the sim800 to start. Then it started working correctly.
Hi I am actually using the module sim808 but i have issues like it does not connect to the network through the sim card and i cannot have access to either the AT command .. If you can help me please !
Ravi Pujar I had already read it ! And actually i am using an arduino to do communication and i had not even be able to have the "OK" answer from any AT that i had send
Where are you using the module in? I mean country. If in USA. I didn't get signal until i changed the CBAND to PCS_MODE when i had sent a SIM808 board to USA. Try that too for network. And also if you are not getting AT command response. I would suggest trying out the terminal using a PC first and then go for Arduino connection. If AT command is not having OK response then you should check the UART connections and also the autobaud settings. If module is in Autobaud mode then you need to send AT command in capital letters for first command.
yss arduino as USB-UART or any other way I just want to upload Bluetooth firmware... actually I connected my arduino with my gsm800 and then using arduino serial port, I am giving AT command without using RS232 or USB..

This method shows you to upload SIMCOM stock firmware.
The SIM800 modules support our own code to be written and programmed in them, But its not officially supported by SIMCOM and hence very less documentation available.
This mean that I can change the functionality of the phy layer i.e modulation scheme or modem synthesizer to change the operating band?
No :)

RS232 uses TX and RX pins itself. But you need either RS232 or USB-UART converter to interface modem to PC for firmware update.
