low power bluetooth module
Hello to all,
I am looking for a bluetooth module with uart interface (only serial port profile needed) for wireless data transfer between two microcontrollers.
But I have the requirement that the power consumption must be very low, less than 1.0mA, in standby mode, that is, in a connectable/discoverable mode (page/inquiry scan).
All the products claim to be "low power", but after reading the small print of dozens of dataheets, I haven't found anyone; the current in page/inquiry scan mode combined with sleep is always of some mA.
Only the single-chip solution STLC2500 from ST seems to have a lower power consumption (0.4mA), but I haven't found any complete module with this chip (although the STLC2500 need only a few extra components, I'm not able to solder BGA I.Cs.).
Does anyone knows any other low power bluetooth module? Any help will be appreciated!
Thanks in advance,
Adolfo.
