Would you consider doing a variant with a larger processor on it? The space on a 168 is very limiting, and upgrading that would make things much nicer for me.
Thank you for your suggestions. How much memory size do you need in your project? We may consider an hardware update if there’s some needs. At present optimizing the RFBee code will get much more memory as Hans has done(Though it is not fully tested) and in for some specific project, the code can be optimized further as some functions are not needed.
