Hello All, I'm not quite sure how to word this question so I will start with what I am trying to achieve.
The RPI will be happily reading data presented to its GPIO and I want to be able to view this data on a standard phone.
The easiest way I can think of is set up the RPI as a web server and create an ad hoc WIFI network. The phone could connect to this network and view the web page.
The problem with this is the user of the phone would have to switch networks every time they want to view the data. This device will be being used where there may or may not be an existing network to connect to so it can rely on joining another WiFi net either.
Is it possible to do this ad hoc networking over blue tooth with the RPI ? Not forgetting I can't install anything other than standard software (ie from the apple or android store) on the phone..as it wont be my phone.
