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

Jessica RodriguezJune 23, 2026
Been integrating the BLE module into a asset tracking build and something's been bugging me. At 50km range the thing is obviously pushing some serious RF power to get there, but most of my actual use cases are sub-500m deployments in a warehouse/yard environment. I'm wondering if the module has any kind of adaptive output power - like does it back off the TX power automatically when the RSSI from the other end is strong, or is it just always hammering at max power regardless of link quality?

@Jessica Rodriguez good question, and honestly one that comes up a lot when people move from "wow it does 50km" to "okay but I'm using this in a building."
 
The short answer is the module doesn't do closed-loop adaptive power control automatically out of the box — it's not negotiating TX power down based on RSSI feedback like some cellular stacks do. But you're not stuck at max power either. The BLE stack exposes TX power configuration, so you can set it manually for your deployment profile. For a sub-500m warehouse environment you'd be massively over-powered at max settings anyway, and backing it off will meaningfully reduce your current draw if you're running on battery.
 
Practically speaking, I'd dial the TX power down to whatever gives you maybe 10-15dB of link margin over your worst-case warehouse geometry, run it there, and you'll save power without touching range performance. The AI firmware builder in the Dev Hub is actually pretty decent for scaffolding the power config logic if you want to wire it to RSSI thresholds and do a soft version of adaptive power yourself — that's definitely doable in firmware and not a heavy lift.
 
What's your power budget looking like on these trackers? That'll determine how much headroom you actually have to play with.
