First HTTP request hangs device

[kevingriffin]

It seems that both of my IRKit units will hang after receiving their first HTTP request (like GET /messages). Looking at the serial monitor in the Arduino IDE, the request is acknowledged but never answered. The unit seems to get a little warm during this time, suggesting some kind of spinning behavior.

Firmware version is the latest (3.0)

Can you write the exact curl command line and curl version that replicates the problem, so that I can try with a unit in hand?

[kevingriffin]

Sure:

curl http://<ip-address>/messages -H "X-Requested-With: curl"

I've been experimenting with the firmware and have found that returning earlier around

device/firmware/src/IRKit/GSwifi.cpp

Line 1226 in f80e837

will cause a crash instead of the unit becoming unresponsive, so I'm iterating around there trying to find the cause.

That curl line is so normal that shouldn't be a common problem for all 12k units shipped so far.
Can you check:

• If AC adaptor and USB cable are fine. I often hear power instability causing IRKit's instability.
• Try another Wi-Fi accesspoint

?

Sure, I'll try to change these things tonight. One thing to add—I have two units, and they both started behaving this way suddenly a few weeks ago.
