This is my first question in Stackoverflow :)
I'm trying to make few modifications to the Ti Sensortag but I have few questions please:
1- is it possible to make the sensortags communicate with each-other without a gateway? (lets Say I put Sensor1 in bedroom 1 and sensor 2 in bedroom 2 can I make them exchange readings without the need for a gateway?)
2- can I install a micro USB over the interface connector to be able to use a portable battery pack? (photo of the interface connector)
thanks
You'll get better more in depth responses on the TI support forums as Ifor has said.
However, I can tell you the answer to #1... Regular bluetooth allows for things like piconets, but Low Energy does not. With LE you have a client/server (master/slave) connection between two devices only. It may be possible to modify the firmware on the sensortags to allow them to make connections to other sensortags, but then they'd have to give up whatever connection they currently had to do so. The master devices can connect to multiple slave devices, but the slave device can only be connected to one master.
As the sensortags are currently designed, I think they only work as a slave (server) device.
