Watch Dogs

What are Watch Dogs?

Watch dogs are smart logic that identifies potential (or sometimes real) issues with the device or the network and pro-actively take some action (such as forcing a reboot) to “self-heal” the device and restore normal operation. Watch dogs are very common in RTLS based devices that rely on customer networks and tag traffic to work or appear to be working normally.

Receiver State Actions Receiver

Types

First Time Bootstrap Unit has not been bootstrapped before.

If unit fails to connect to predefined SSID (mpact_init) (retry delay 2 min) or unit fails to pull bootstrap configuration(badge_config.json) (retry delay 2 min) the unit will keep retrying.

First Time Bootstrap Unit has not been bootstrapped before.

If unit fails to connect to predefined SSID (mpact_init) (retry delay 2 min) or unit fails to pull bootstrap configuration(badge_config.json) (retry delay 2 min) the unit will retry for a maximum of 3 times.

After which it will shut down and power off the battery.

Normal Operating State

Unit has been configured before and gets rebooted for some reason.

When it tries to initialize and join the network and fails five times (2 min delay between retry) then the unit is rebooted.

Unit upon reboot tries to pull its configuration (receiver configuration).

If configuration pull fails, retries are done after one minute delay.

If receiver is unable to pull configuration even after 5 attempts then it is rebooted.

Unit upon reboot tries to pull its time information from gateway.

If time pull fails, retries are done after one minute delay.

If receiver is unable to pull time information even after 5 attempts then it is rebooted.

Both

Normal Operating State

If 3 consecutive heartbeat posts to gateway fail then the unit is rebooted. Both

If there is no heap space available to create a thread to process BLE Beacons then the unit is rebooted

If there is no heap space available to create a thread to store data in external SRAM then the unit is rebooted

If there is no heap space available to create a thread to post beacon data to gateway then the unit is rebooted

When receiver runs out of heap space trying to process response for time request from gateway then it is rebooted.

Normal Operating State

When receiver runs out of heap space trying to process response for configuration request from gateway then it is rebooted.

WIFI Network check watchdog is started upon unit start.

The health of the network is checked every 2 minutes. If 5 consecutive network check fails unit is rebooted.

Unit registers for asynchronous link up and link down events from WICED WIFI.

If link down is received by the unit then the unit tries to re-initialize the WIFI network a maximum of 5 times with a delay of 1 minute.

If even after retries the network initialization fails the unit is rebooted. Note, if the unit receives link up event during its retry the normal processing is started.
