Arming the device and initiating the downlink

Downlink

Before you start working with the device, make sure the settings you want to change are input into the Sigfox backend (or IO Frog/other platform) and saved there = waiting for a downlink request.

Downlink Informationchevron-right

Please note that SimpleLeak currently supports only one mode - Leak detector (0x0A). Changing the mode is not recommended as the device will not be able to switch back to Leak detector! Please use the downlink only for the fine-tuning settings of the Leak detector mode.

  1. Place the device onto a plate with some water (at least 2mm) and wait until it beeps twice - this indicates the start of arming (downlink is requested with this message as there’s no control button on the device).

  2. Remove the device from water and wait for the departure delay timer to expire (15 seconds in default).

  3. After departure delay, the SimpleLeak will beep three times. This indicates that the device is armed.

When arming the SimpleLeak, you need to see this on the Sigfox backend:

  1. Uplink message with 0x0A (Leak detector mode) as the first byte and 0x10 (Start of arming) as the second byte. You should also see that the message requested a downlink.

  2. You should see ACKED when you click on the downlink arrow - this means that the BTS sent the downlink to the device (which does NOT mean that the device received the downlink!)

  3. Uplink message with 0x0A (Leak detector mode) as the first byte and 0x11 (Armed) as the second byte.

Disarming the device

  1. Simply flip the device upside down and wait. When it stops beeping, the SimpleLeak is deactivated.

When disarming the SimpleLeak, you need to see this on the Sigfox backend:

  1. Uplink message starting with 0x0A (Leak detector mode) and followed by 0x14 (Disarmed).
