Struggle to connect 2 bluetooth devices on android
So here's my problem:
I'm trying to develop an app for android that conects MindWave Mobile from Neurosky (an EEG headset) and Sphero (spherical robot) to the android device. I'm utilizing the NeuroSkyUnityThinkGearPlugins for the MindWave Mobile and the Sphero Unity Plugin for Sphero.
Everything works fine individually but when I add to the DisplayData script the options to connect the Sphero and try on the app, it doesnt connect the MindWave Mobile, only the Sphero device.
In terms of hardware I utilize a Gionee CTRL v4s version 4.4 android that as a bluetooth 4.0, which means in theory it is LE (Low Energy) and can in theory connect multiple bluetooth devices.
So my question is what should I do to connect both of them??
Aditionally if I can connect both of them, I can afterwards make them interact with each other right? That is, use the MindWave Mobile as an input source, the android device gets it and processes it and afterwards sends the output to the Sphero device.
Hmmm... I'm not well versed in bluetooth, but without using Unity at all, can you pair your phone to both devices? $$anonymous$$aybe the phone is only able to pair to one at a time, in which case Unity won't be able to override that.
Aparently yeah, at least when I try to pair both of them to device I can successfully pair them and stay both paired.
it may be a limitation of the android device. the BTLE stacks in those devices vary a lot, and some of them are just not very good.
if so then what android device do you know that works with multiple bluetooth connections?
unfortunately this information is not documented, in my experience. i'm unfamiliar w/ the device you mention.
but @fortisvenaliter's suggestion is good.
