we had similar problems with voltages on a original CSR module, it was
specified as 3.3V type (+- 0.1V) but only worked at 3.15V. it was
reproduceable with 3 modules, and tests showed that the casira unit also
outputs 3.15V to the module. my hardware technician is not here to ask him
for more details, i am only slightly involved in the hardware development.
powered with 3.3V i was not able (or better to say not reproduceable able)
to find other devices (and get their BT name). i dont use the openBT but
only onchip routines.
