Check which firmware you have in yourВ SIM900A GSM GPRS mini board. Firmware can be for 32 and 64 version of chip.You can see the ST_ENHANCE and ST on the end вЂ“ ST means standard versionВ of firmware, ST_ENHANCE вЂ“ means enhanceВ ( extended) versionВ of firmware.Make sure that you have USB to TTL converter.ДЇirmware versions:В You can check them here.You can check for new versions SIM900 here. If you decided to do it make sure that the next firmware version which you are planing to upload is not older than existing.Just think if you really need to do it as it is a risk to damage the module!!!.Read all information about firmware update available on Web.Always make sure that you have your firmware version on hands so you can restore previous version if next firmware version is bad, for example we had previous versionВ 1137B11SIM900A64_ST.

If you check it with command вЂњ AT+ITR?вЂќ вЂ“ it will return: вЂњ+IPR:115200 OKвЂќ

Returns the TA Revision Identification of Software Release of the module, for example: вЂњRevision:1137B11SIM900A64_ST OKвЂќ.В Set baud rate to 115200 bps (ItвЂ™s 19200 by default) Enter вЂњ AT+IPR=115200вЂќ and press SendВ button.

Follow the steps as described before here: Basics: Project 105a SIM900A GSM GPRS mini module.

If unused keep open.Д¬onfiguring the SIM900A GSM GPRS mini board with USB to TTL converter

NRESET вЂ“ External reset input (Active low).

ADC вЂ“ General purpose analog to digital converter.

Maximum cable length 200mm from the module pad to SIM card holder. All signals of SIM interface are protected against ESD with a TVS diode array. The voltage can be select by software automatically either 1.8V or 3V

SIM_VDD вЂ“ Voltage supply for SIM card.

#Simcom flash update tool v1 10 serial#

DBG_RXD вЂ“ Serial interface for debugging and firmware upgrade.

DBG_TXD вЂ“ Serial interface for debugging and firmware upgrade.

Pull up to VDD_EXT, if unused keep pins open

DISP_DATA DISP _CLK DISP _CS DISP _D/C вЂ“ Display interface.

SPK_P SPK_N вЂ“ Positive and negative voice band output.

MIC_P MIC_N вЂ“ Positive and negative voice band input.

PWRKEY_OUT вЂ“ Connecting PWRKEY and PWRKEY_OUT for a short time then release also can power on or power off the module.

The user should keep pressing the key for a short time when power on or power off the system because the system need margin time in order to assert the software. PWRKEY should be pulled low to power on or power off the system. If the RTC function is enabled, a battery or capacitor should be connected with the VRTC pin. Current output for backup battery when the main battery is present and the backup battery is in low voltage state.

VRTC вЂ“ Current input for RTC when the battery is not supplied for the system.

It must be able to provide sufficient current in a transmit burst which is typically rises to 2A The power supply of SIM900A has to be a single voltage source of VBAT= 3.4VвЂ¦4.5V.

VBAT вЂ“ 3 VBAT pins are dedicated to connect the supply voltage.
