I plan a project which should run in my car and provide the following functionality.
Use my mobile phone to:
a.) Send information (text) to the “device” which will then be sent out via serial port
b.) Post information from the device to a connected phone
My idea is to run some kind of “Web server” or socket communication or…
Anyhow my question is hardware related.
For me it looks as the easiest to have a wifi hotspot where I can connect to with my phone.
Which hardware should (can) I choose?
I think about the spider as mainboard, but I’m not sure if the RS21 can act as hotspot.
Or is BT a better option?
Is there a bluetooth module (couldn’t find one)?
My phone runs windows phone 8.1
