OTOH, > the range is way over what we need, A quick thought - did you know you can set the transmit power level? Default is 0 dBm, which I believe is what the peak current consumption figure is based on, but you can dial it back to -10 dBm. Maybe MaxStream could tell you what difference that makes; if not, you could run some tests. (I may be available if you want help with that, but not for the next couple of weeks at least - let me know off-list if you're interested.) -- Timothy J.
