I have been running the os_219_5_enc28j60_debug firmware and had my first unresponsive event.
The symptoms I observe:
The OpenSprinkler is not responsive when opening the webpage and the web browser times out.
The TestOSAPI utility also times out. “ERROR! IP/port not reacheable or timeout happened!”
However, the OpenSprinkler continues to respond to pings normally.
The OpenSprinkler’s clock continues to be accurate.
The OpenSprinkler continues to run programs and water normally.
DHCP is turned off in the OpenSprinkler.
The debug information shown after a reboot when responding normally:
28|1|4|B0|0|31
The debug information shown after the OpenSprinkler becomes unresponsive:
28|13|4|B0|0|31
