bluetooth booster / battery monitor

hi and wondering if u guys would be so kind to help please

bought this battery monitor and works on my ipad via bluetooth , version 4

have the base model D3 so no built in bluetooth , was wondering if i convert one of the cig lighter to a permanent live is there such a thing as a bluetooth booster that i could then plug in to boost the bluetooth signal between the battery monitor and ipad plse

does say 10 x metres range , but in reality is around 15 x feet and would just be nice if there was some kind of booster device that i could plug inside the D3 plse

alas , won’t have any data yet and just got to secure the unit properly

many thks as always in advance

ps, just thought i wonder if there’s something i could plug into the OBD2 port to boost a bluetooth signal , or maybe if there’s such a thing as a bluetooth repeater for the ipad side ????

By its very nature and design, Bluetooth is a very short range service. I think you might be hard pressed to find a "Bluetooth booster" as you can for wifi.
Looking at your pictures, one thing I can see which might help is that your battery condition tester box is a bit screened in the location where you've placed it, especially when the bonnet is closed. Bluetooth is, after all just another type of radio signal and the range of transmission will be improved by installing the device in an optimum location.

thks, was wondering if it would make any difference if i take the units neg side off the body earth and put it onto the battery neg post , therefore allowing the unit to be mounted outside of the cover ??

suppose it can’t hurt trying it

it was just in the off chance , ie like a repeater / booster etc

thks again

Funny.... my Bluetooth Motorbike intercom works at up to 1Km in LOS. So I don't think BT is necessarily that short-range

Try anything you can think of, looking at the device, there are only the two wires so you can't reaally go wrong, Remember it isn't going to transmit to its best range while you have it located inside a metal box.

I don't know what the radiator grille on the D3 is made of, sheet metal or plastic, but I would be tempted to try to get it as close to open air as possible such as behind the grille. That would obviously mean extending the two leads and also arranging some method of preventing moisture ingress.

The bluetooth transmitting element (the aerial) is built onto the circuit board inside the device, consequently you should look at using some sort of non-metalic enclosure to moisture proof the device.

great idea , ref the front grill which is plastic i could indeed extend the wires , installing it inside a small waterproof box ...

OR

following on from ur great idea, recently fitted a 12s towing socket which i recharge my batteries through , connections inside are right by the boots side glass , so no issues with water getting onto it

but certainally a great idea you’ve got ref extending the wires and putting it into a better position

nice one and cheers for that

Gary has already said that the details for the device state a working range of 10 metres, which according to official figures would place it in "class 2" of the Bluetooth regulations. Like all radio installaions, its operation would depend on many external factors if optimum results are to be obtained.
But in spite of your claim of 1 km for your device, which I don't dispute, Bluetooth is classed as a very short range radio system utilising a very low power transmitter.

I didn't mean it was high power Brian, just that in open air LOS the BTS/2 (clue to the BT version I guess) works very well and are 8 hours of comms on their tiny internal battery. The clarity is just amazing. I was well impressed.
The OP's device may be only able to transmit 10 metres as you say.

apologises , for full info , this is the one i bought
