I have given GraspIO a try as it seems to offer easy development via mobile phone and free IoT cloud calls
The IO and sensor, plus a little screen makes it useful
i plug it to a raspbeerry pi 3 B+, put in a 8GB microSD card with graspIO image and power it up.
it starts blinking
after what seems like 10 minutes...i not sure why it takes so long.
And end up i get this error with the exclamation mark. There is little help or reference i can get from graspio documentation
unsure why, i reflash my microSD retry a few times the process above without luck
i suspect that Raspberry Pi 3 B+ , which is what i am using, is not supported. However,
it is not mentioned clearly whether it is supported on graspIo site. i would says the documentation is a little bit
unfriendly to novice user like me
after wasting few hours, i found a raspberry pi model b+, i try on it and it works.
