Turning on brownout detection did the trick. The voltage at the chip via the serial line was about 3.2v so setting BOD to 4.3 keeps the chip from staying awake when the power switch is turned off.

I use the HM-TR modules as well. One thing I discovered, you get much more reliable performance if you pull Enable high. I think the internal pullup resistor is a high ohm value since just touching t ...

I went to purchase some Mega32s and found a new chip, the ATMega32A at a much lower price point (almost half the cost of the original Mega32!). It appears to be identical to the Mega32 but you know ho ...
