It is advised by SIMCOM that the baud rate of the module be set to 115200 bps before firmware upgrade process.

Once you have connected the UART lines of SIM800 to your PC and it is detected as COM port in Device manager utility as shown below ( In my case i am using a Silicon labs USB-UART converter), Note down the COM port number, which here is COM8. Because the MCU program which will also be sending data on UART to SIM800 might interfere with the firmware upload process which is also happening on same UART lines.

If you are using a micro controller on board connected to these UART lines of SIM800 then it is better to update the firmware of SIM800 first before programming the MCU for first time. Most of the projects have UART lines of SIMCOM modules routed to a connector, if not it will be advised to do so because you will need them to program the firmware of the module. When download will be finished and status will become DL OK and takes around 26 seconds to completeįor updating the firmware through the UARTlines of SIM800 we need to connect the UART data lines ( UART_TX, UART_RX) and power key line ( PWRKEY) to a PC or laptop using a USB to UART converter or RS232 converter, so that the data can be sent to SIM800 module using a COM port. cfg file from firmware image downloaded above by clicking on Image Folder button,Ĭlick on Start download button and power on the SIM800 module and download should start Select the Firmware update method to USB,īrowse and select the. Select the SIM800 module which you have on your board, Once you have connected the USB lines of SIM800 to your PC, Open up the SIM800 firmware update tool you downloaded above, So that, later when board is ready you can just plug in the USB cable and update the firmware of the SIM800 module straight away. If you have designed or thinking to design a board using any of SIM800 modules then it would be wiser to leave out the above mentioned USB lines to a USB connector. UART Interface : Slower, Needs 3 lines of SIM800 module, UART_TX, UART_RX, PWRKEY and GND connectionįor updating the firmware through the USB lines of SIM800 we need to connect the USB data lines ( USB_DN, USB_DP) and USB power line ( USB_VBUS) to a PC or laptop using a USB connector.
USB Interface : Faster, Needs 3 lines of SIM800 module, USB_DN, USB_DP, USB_VBUS and GND connection We can program a new firmware image to our SIM800 module using either UART interface or USB interface. First download the tools, files and documents used for the firmware update from the below links,
