“Up- and downstream transmission in the network follows two different principles:
1. On transmitting from a Gateway, the receiving device is allowed to receive and act on a packet that is received with valid CRC regardless of whether the packet is received from the Gateway device directly, or if received from the router device that is the normal transmission path.
2. On transmitting to the Gateway, the path is determined and may not be circumvented.
As a consequence of above, you may sometimes observe the below pattern. The Gateway is able to communicate directly to an end device / router, whereas the communication in the opposite direction always goes through an intermediate router.
The RSSI acceptance level controls the minimum signal strength required to create a link in the network. By increasing this level, you will increase the likelihood that a Router will connect on fewer hops / connect directly to the Gateway. On the negative side, this will tend to reduce network stability.
By setting the End device to transmit in ‘walk by’ mode, the End Device will not utilize the normal hop path, as it will not be expecting an ack from the receiving node. In this mode, you will probably experience that in most cases, the End Device packets will directly reach the Gateway device in both communication directions ( up- and downstream)
