How long have I been asking you to check your receiver config?  And
still nothing sent to this list.  At least some progress.

I already pointed you to driver_ubx.c, ubx_cfg_prt(), where gpsd sents
stuff up.

Did you look at those?

Don't guess.  Look at the code.

I've been thinking of splitting the "-b" into two options.  One
for no data sent to the receiver (bluetooth mode), and one for just
no reconfig sent to the device.

A start.  I continue to suspect you have other config that needs setting
as well.  Still waiting your config dump.
