Another option that is worth exploring is the free Visual Studio Arduino plugin. Aside from a host of useful code explorer and intellisense features it clearly shows code as enabled or disabled based upon #defines. This makes it much easier to see source code that is used only when debug is enabled. http://www.visualmicro.com

There are also some useful arduino source code debug trace and/or step features to be released June 2012. http://www.visualmicro.com/post/2012/05/05/Debug-Arduino-Overview.aspx

I have another question related to your point about putting a switch on the TX line. I am trying to design a board where a UART peripheral is permanently connected to the Arduino RX/TX lines, but it is still possible to upload sketches via USB.

I tried to design a circuit using an optocoupler that will allow the board to automatically disconnect the peripheral’s TX line when the USB is plugged in, so that the upload process doesn’t damage the peripheral and the peripheral doesn’t interfere with upload. Details here: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1284939455

Would love to get your feedback on this. Is this a reasonable approach? Is there a better way? Is disconnecting the TX correct, or should I simply depower the peripheral or disconnect the RX? Some combination? Many thanks!

BTW. The GSM module cannot be powered by USB ; your powersupply needs to handle 3A surges.

I don’t really understand why two USB adapters are necessary. Is it because you are using the 1st one just to power the project? Couldn’t you use a single USB adapter to upload your firmware, then remove it and plug it into the SoftwareSerial ports, then power the project off a 9V or something?

With a single UART I’d try what SJ describes in the blog entry we are commented on.

I recommend using hardware serial for control of the modem and software serial for debugging. Good luck. BTW. I would like to start an open source project for creating an Arduino C library for the Telit AT commands. Let me know if you’re interested?

I guess I need to find another AVR with dual hardware UART. The atmega 168 processing power and # of IO pins are enough so i need to upgrade only because the UART :(

Any recommendation of an AVR with dual hardware UART, the 128 is overkill? I will google it but maybe you have a recommendation.

Thx for your time.

That is where I run into a problem, reading the AT commands responses. If you’re OK with sending an SMS and not reading the response, then you should be fine.

You said that you have experience problems using the library.
Right now the project that i’m working on needs the use of the software serial library to interface with GM862 to only send and receive SMS messages (not planning to run on 8Mhz), no GPS or GPRS.

Do you think it will be a problem based on your experience?

Thx
