Programming SIM808 (Program loading is an unsuccessful)

Hello Arduiners

I bought recently the GPRS Module SIM808 because i have plants to create a tracker in my car.

I remember that i saw in Youtube a developer uploading a program directly to this module, using in the board manager the board "Arduino Pro or Pro Mini" and, on this video, he did the upload and the boards worked perfectly.

Unfortunately i lost the web address of the video but i followed all the steps he did.

When i tried to upload the sample sketch to test the board, the debugging step is finished but the loading fails and the IDE shows the following message:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xe4
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0xa5

avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00

I already tried to use all the available programmers but nothing is working!

Does anybody could help me?

Thanks in advance!

Which Arduino are you using?

Is your module connected to pins 0 and 1? On most Arduinos that would interfere with uploads in which case the advise is to disconnect the module, upload and connect the module again.

No! I'm using the USB cable directly in the module!

Link to the module please.

Is this one!

OK

The USB port on the board is for a firmware update. Maybe via this link your can find the video back: sim808 firmware update - Google Search

I can't help you further, sorry.
