Re: Bluetooth chip question

Je-Rock

I've used National Semiconductor LMX 9820A Bluetooth Serial Port
Module. I worked on the software on a mircoprocessor which talks to the
chip via UART. It works well. Though the BGA took a friend a little
fiddling to get soldered.

An external Antenna is fittered. Not sure what type. Its not on the
schematic.

I've thought about using a board already made with an complete solution
for bluetooth because I was worried about the success of the BGA.
