Just thought I would mention this as I was having a memory leak problem
and I have no prior AVR experience being a PIC programmer.

Having just read the programming style guide on the Libelium site it
says that sprintf must only be called once per function ...

If you call it more than once you will get a MEMORY LEAK !!!!!

Just sent for those who dont enjoy 12 hour days.

robinaspey,

As you say, and also as it is said in programming style guide, sprintf function must be used with caution. Otherwise can cause problems (but not always).

Best way is use "callocs" to allocate memory and do "free" after the usage.

If you are having some trouble with this, please follow advises given in the programming style guide. It is a bit messy, but it should works.

Best regards.

Ok thanks, I agree its a bit message but such things are to be expected with
embedded systems.

I am happy, I can have my holiday now!
