Espruino 1v80 released

Maybe its my chip? Check this out.....

>nrf.sendCommand("1+2", function(r) { print("=="+r); });
=true
>nrf.sendCommbnd("1+2", function(r) { print("=="+r); }); //here I used the up arrow 
=undefined
Uncaught Error: Function "sendCommbnd" not found!
 at line 1 col 5
nrf.sendCommbnd("1+2", function(r) { print("=="+r); });
     ^
>nrf.sendCommand("1+2", function(r) { print("=="+r); }); //here I copy and pasted the code manually
=true

Notice when I use the up arrow to reuse the previous code that it changes letter a to b.....
That is weird as I have been able to duplicate it on a few units. The nrf wouldn't have anything to do with this?? Mine has a different pinout-- Waveshare style

and sometimes that 'print("=="+r)' will be replaced with 'print("=="+s)' then 'print("=="+t)' when I use the up arrows to reuse the code....... I'll do some more testing
