MultiNav Pro+ BLE - does output power scale down automatically at short range?

Joseph JonesJune 23, 2026
Been working on a tracker build using the MultiNav Pro+ BLE module and something's been bugging me. I know the module is specced for 50km range which is obviously the headline feature, but in my use case most of the time the nodes are going to be within like 50-200 meters of each other. What I'm wondering is whether the module does any kind of automatic TX power management based on RSSI or link quality, or if it's just always blasting at full power regardless of how close the devices actually are.

@Joseph Jones honest answer — I don't have a definitive spec sheet confirmation on whether the MultiNav Pro+ has automatic TX power scaling built in at the firmware level. The module is designed around maximizing range so it's likely running at full power by default, but whether there's an RSSI-based backoff happening automatically is something worth getting a direct answer on rather than me guessing.
 
What I'd do is either ping Moamen directly through the Dev Hub or dig into the AI Firmware Builder and ask it specifically about TX power control via the SDK — if the hardware supports adjustable output power registers, you can almost certainly implement your own closed-loop power management based on RSSI readings even if there's no automatic mode out of the box. For a tracker build where your nodes are sitting at 50-200m most of the time, manually stepping down TX power when RSSI is strong would save you meaningful battery life.
 
Tagging this for Moamen's attention too since it's a good question that probably affects anyone doing dense indoor or short-range deployments with this module.
