FRB6.5 Wrote:On another Labradar reliability tangent; Bluetooth.
If using an external battery the quality and wire thickness of the USB cable used does affect Bluetooth. I believe it may have been mentioned on the forum before but I can confirm the cable does matter.
I had a short, right angle USB cable so it wouldn't get tangled and to reduce chances of snagging or damaging the socket. The cable was on the thin side. While I never had any other issues with the Labradar's function ore reliability, Bluetooth was erratic at best. I switched out to a longer, very thick 24ga. USB cable and Bluetooth was rock solid, it didn't drop a single time over a two hour period.
Never had any Bluetooth issues other than the connection dropping out when the IPhone goes to sleep...all too often. My lead is at least 1M. Are you thinking the thin lead was not shielded and it was RF interference? This is the lead I use, a 24AWG

Do you think the radar will take 8.3V via the USB port? In the picture you can see the DC: DC voltage regulator in between the Li-ion battery and radar. The regulator drops the fully charged Li-ion pack from 8.3V to 5V. Surely there is an internal regulator in the radar. The internal battery compartment takes 6 x 1.5V AA in what looks like series = 9V so I'm tempted to try 8.3V directly from the battery pack.
