Bluetooth uses the same frequency as Wifi (2.4GHz). Its obviously possible to measure WiFi signal so it should also be possible to measure BlueTooth as well. The problem would be if SE doesn't incorporate the ability in the BT FW or driver. Then, there is nothing a developer could do to get that info and display it on the screen.

I know that in the BT RFC it talks about being able to do it and there is a spec.

I don't have the dev paper from SE with the info, if I did, and they follow the spec, it would be quite easy to write.

ha, yes, I've seen that one. I have a billionton bluetooth dongle which uses the widcomm drivers. of course its only a rough gage but I guess that is one answer

well remembered!

might be interesting to have the device vibrate or beep if you're about to move out of range or lose signal for some reason

although the idea is good, im afraid its not practical at all ! you see, this requires "dynamic monitoring". an example of this in programming is "events" where the status of application buttons or the computer mouse are continously checked. this is not practical in phones because phones are power dependant (battaries) and dont have powerful processors to implement more dynamic monitoring than that they are currently doing.

@calsb3rg , in my opinion its not going to work also, bluetooth (radio) signals are "radial", i.e. 3D propagated. since i know what were you going to use that "theoratical" programme for ; have you considered what will the phone show you if the girl was exactly below/above you a level !?

This is the long way round but you can using FMA to check signal

I've got an hx4700 too and you can see the signal strength of active Bluetooth connections.

When you've got a Bluetooth device connected (eg Headset, PC) go to the "Active Connections" tab in the Bluetooth Manager. Tap and hold on the connection and choose "Status" and it will show you the signal strength.

I've never known a signal to be described as 'Too Strong' before!

I can see that if the signal's good, the devices can afford to power down a bit to save batteries, but that hardly means it's too strong to communicate.

Can someone explain this counterintuitive description?

Its also worth bearing in mind that bluetooth is only really designed to work in what, a 10ft radius? Whilst I like the idea of a signal strength indicator, its such a small area of space that its pretty simply to estimate wouldnt you say?

If I'm 1ft away from you then excellent signal, 5ft medium and 10ft poor signal. For example.

Er....isn't it 10 metres? And I've been hearing this 100m bluetooth thing too! This message was posted from a T230
