Re: Not recieving packets when car is on
|
When you say "... decode rate plummets to almost nothing." , how do you know if it is decoding? I am guessing you are actually referring to no decoded packets received through Bluetooth (BT).
Does your car have a Bluetooth connection to your phone? You may have to turn that off so that the communication between the TT4 BT and packet device can communicate. Did this TT4 setup in this same car work okay prior to the BT?
If you don't know, try the setup without the TT4 BT (hardware) interface. ?? If that works, then the real issue is the Bluetooth is being interfered with.

thanks, I'll try an AM radio.?
The TT4 and radio are tied directly to the battery with adequate gauged wire. I'll try the separate?battery idea!?

Grounds and power for radio, BT, TT4 to the car battery with right size wire? I have sizable wire for radio directly to car battery with BT and TT4 tapped off of it. If an older car the spark plug wires could be an issue.

The problem I am having is that when the engine is on, my packet decode rate plummets to almost nothing. If the engine is off, there is no issues. I assume that this is an RFI issue. When I listen to the radio with the engine on, I cannot hear any noticeable RFI over the speaker but I assume that this issue would not be detectable audibly like this. Suggestions on where to look? I added ferrites to all the TT4 cables to no avail. Thanks!?
