Using AT24C02A EEPROM

eeprom.a() should return a 1 or 2 byte string, not a native code function. In this case it should return: "P".

This is pure JS - it has nothing to do with the connected device.

I also cannot reproduce that behavior on my system - I get the correct results...

console.log(eeprom.a(eeprom.i2ca));
P

What version of Espruino firmware are you using?

I'm also PMing Gordon, maybe he might have some insight here.
