Maximum hops for broadcast

I have a XBee PRO 900HP and wanted to confirm my understanding of BH (Broadcast Hops) and NH (Network Hops) configuration for a broadcast oriented network.

The BH parameter states “The maximum transmission hops for broadcast data transmissions. Set the value to 0 for maximum hops. If BH is set greater than NH then the value of NH is used.” The range for the value is set from 0x0 - 0x20 with the default being 0. So would this default 0 be considered decimal value 32 (0x20) since it is maximum?

The NH default value is 7, so I am unsure if the BH value 0 is considered greater than NH 7 since the value 0 for BH is maximum.

I am in a situation where I may need to have a broadcast be repeated more than 7 times, so I am not sure if the NH value of 7 is going to be considered a limiting value with the BH set to 0.

So in that case, you would want to set the NH to the largest value supported (0x20).

If I have a network that may need 8-10 hops using repeaters to fully cover the range of my approx 25 devices that wake up and broadcast a small data sample every 10 minutes, would that still be within acceptable limits in terms of bandwidth and number of hops?

Then setting the NH to A would be sufficient.

Thanks for the info. I’ll move forward with that.
