V4 + basicstation do not reach DR6 or DR7

ChirpStack Gateway Bridge
1

I have recently migrated a network based on RAK7240 working as LNS, to one using a variety of gateways working as BasicStations connected to a central Chirpstack V4.

In my previous setup, devices will be sending most of the time in DR7, but in the new one devices never pass DR5, with any kind of gateway.

I have modified region_eu868.toml: [only enabled region]
[regions.network]

# ADR is disabled.
adr_disabled=false

# Minimum data-rate.
min_dr=0

# Maximum data-rate.
max_dr=7

But no success.

I also tried setting:
Device Profile → ADR Algorithm → Lora & LR-FHSS ADR Algorithm.

Also no success.

Not sure which other configuration may be needed.

Any suggestion?

Thanks!

I believe the ADR algorithm does only increase up to DR5, it does not work for FSK. You might want to implement a custom ADR algorithm if you would like to use DR > 5.
