In 19200 baud, the firmware updater keeps sending decimal 255 and never receives a response. I have now tried to run the updater in 19200 bauds, and listened in. OK, as I said, I didn't use the PWRKEY button, I used a jumper to connect pin 1 directly to GND. In this way, you don't need to pushing button all the time.Д«y the way, when push the PWRKEY button PIN1 and PIN2 of SIM900 are connect together.

This afternoon I will probably try to connect the logic analyzer again to see exactly what the update tool sends over the wire.

I did not use the button for the upgrade process. I did actually connect PIN1 directly to GND and nothing else, as I described.

By the way, when push the PWRKEY button PIN1 and PIN2 of SIM900 are connect together. In this way, you don't need to pushing button all the time. Is there a different sequence of steps I should try? Can I ask which baud rate you use for firmware updates? Edited to attach a photo of the setup the TX and RX pins are only connected to my USB/TTL thing at the top left. Also in every case, the Netlight and Status LEDs light up like they would normally do, and Netlight does off after 10-15 seconds. Connect GND to pin 1 (PWRKEY), hold it there.Д®very time, no reaction from the firmware updater.Pres START in the updater, wait for 'Please power up the target' message.While PWRKEY is still connected to GND, press START in the updater.Д®very time I get the message 'Please power up the target', at which point nothing happens.Connect GND to pin 1 (PWRKEY) on SIM900 with jumper wire, hold it there (at this point the board starts powering up normally, netlight and status light up as if I had just preseed the button).For the various baud rates up to 115200, I do this:

Separate jumper wire that I use to connect GND directly to pin 1 on the SIM900 chip.

I assume these go through the level shifter.

TX and RX directly to the USB/TTL cable from the GPRS_TX and GPRS_RX pins.

GPRS Shield power provided from a Seeduino.

This worked, I received the SMS, but again (as usual) I never receive a response from the GPRS Shield to AT commands. To test that my UART cable works, I used a terminal emulator to send an SMS. I connected the GPRS Shield to a USB to TTL UART cable that I obtained here. After you connect the wire(here PWRKEY(PIN 1) of SIM900 should be connected to GND during the whole process), first press START of Simcom - sim900 Customer flash loader V1.01 (before this process the module is power down, completely disconnect from any power) then power up the module( connect to power ). GPRS_TX and GPRS_RX should disconnect from other purpose. Jimbo.we wrote:You can use the use the GPRS_TX and GPRS_RX pins with UartSBee or equal.
