When I like to upload the sketch on the board. It shows a serie of errors on IDE Arduino. Can you tell me the set configurations that i should do. I'm using usb to ttl board to connect the board with the pc. I think the mistake is for the bootloader of IDE. Help me pls.


May I ask you why you had use a voltage regulator when you powered the board with 12V? and can you upload the schematic please ( that green tiny circuit in the first pic.

Very helpful. I was pulling my hair out (not that I have much left) trying to get my Gboard to power-up and send a text message. I have a prior application on an Arduino UNO that I want to port to the Gboard and your post helps alot. I modified the task_sendBal() to just send the word "test" to my personal cell phone and it worked great. I am using a TruPhone sim so the number 222 did not work for me.

Now that I know my Gboard works, I can modify my Uno sketch to work with Gboard.

Thanks for your help.

Everyone should please follow these coding best practices in their Sketch.

If you find yourself asking "should I comment this code?"… the answer is always "yes" (and yes, you should always be asking yourself that).

Simplified the versioning of source for our basic needs. Should be easy to follow. Thanks for the question!
