Dear Power_Broker, thanks for the proposed alternative.
Just a quick question:
As you may see on the receiving sketch above the big problem of the method I am using is of data types.
//ftp.WriteData(buf, sizeof(buf));
//*invalid conversion from 'const char' to 'unsigned char' [-fpermissive]
The ftp.WriteData function requites unsigned char to work.
Any idea how will I recompose and convert the arriving data into this data format?
Thanks
Paulo
