I am a newbie in sparkcore. So please excuse me if this sounds a petty issue.
I want to do a deep update for the spark firmware as I read on forums that its necessary to do so if you want to get connected to a webpage. However, while doing so I get the following error:
Apparently I didn’t find a DFU device? util said
Error writing firmware… no dfu device found.
I have kept the core in dfu mode(the led blinks yellow). Still I cannot do the update. Also now after trying to do this update for several times, I cannot connect to the core anymore. Even after doing a factory reset.
Please suggest me. I am kind of lost now. As I am new to all this, I am not very sure which direction to proceed now.
You are going to want to look at http://docs.spark.io/firmware/#communication-tcpclient but I think this would be best done in it’s own thread (for easy searching). Would you mind creating a new topic if you have questions about connecting to a web page? I’m going to make this “solved” for now. Feel free to comment back if you have additional deep update issues.
