Case 354

[James]

Question:
When does a wireless logger switch to another gateway?

Possible Root Cause:

1. In the software V1.3.1, the allocate gateway occurs when the current gateway didn't receive any values.
2. In the software V1.3.1, the allocate gateway occurs when the RSSI difference is too big.

Solution:

1. Update to the software V2.1.0. Please see the RMS-2533 input in the change control. In the Software V2.1 the average of the last 5 RSSI values are taken before reallocating the gateway. If one value is missing the average RSSI value will be reduced by 10. The gateway is switched if the difference is >=15dBm (or 10dBm if the RSSI >=-90dBm).

Additional Information:
The event in the audit trail is allocate gateway.
