Looking at the settings in XCTU, I see the value for NH (Network Hops) is set to 7.
For one of our deployments we may need to have more hops to reach the modem and I was thinking of setting the value to hex value A to increase that max number of hops value.
From my understanding both the modem, repeaters, and the nodes themselves have to have the same NH value for the max number of hops value to work correctly. If that is correct, does Alpha Station or the library for Node-Red provide a way to set the NH value or would I need to remove each xbee module from the nodes and plug it in a USB board to set the value in XCTU?
Hi @duelingcats Could you elaborate a bit more about your application and industrial environment?
For your reference,The DigiMesh protocol we utilize is only rated for up to 8 hops. So you can have up to 7 repeaters between the sensor and the Gateway/Modem.
Thanks,

My environment requires lower power levels (PL value set to 2) and hence lower range as well an environment that is difficult to get signal through. Those two things combined have made range an issue with our initial deployment and required a few repeaters. We are planning for the next larger deployment to have the same issues.
From what I was reading I thought the max number of hops was 32.
Looking at Digi’s Documentation here I see the same you are mentioning @duelingcats
https://docs.digi.com/resources/documentation/digidocs/90002173/#reference/r_cmd_nh.htm?TocPath=AT%2520commands%257CNetwork%2520commands%257C_____3
Take a look at NH under AT Commands/Network.
I’ll see if I can confirm this with Digi but previously the number of hops was limited to 8 as Eduardo mentioned.
@TravisE_NCD_Technica Yes I had ask Digi about the settings a few months ago in this thread Maximum hops for broadcast - XBee - DigiMesh - Digi Technical Support Forums but wanted to confirm that setting that value wouldn’t mess up anything on the embedded NCD software side of things.

To my knowledge it would not mess anything up on our end. I would be curious to know your findings. Keep us posted.
