Pulling data from ELM327
<p>am developing an application where I can get data from ELM327 and display it on an android device.But I have a doubt,the ELM327 is not controllable,I mean it cant keep sending data automatically to the android device,so how would I be able to pull data from the ELM327.I am really stuck here.So help would be appreciated.Thank you!</p>

<p>Can anyone help me with the type of commands I have to use in android to get responses from ELM 327?How would I only receive speed and rpm?How can I read that data and display it on the android device?</p>
