ADR RN2483: can't set off

Good evening,
I am writing to you for a trouble.
I have an RN2483 module. When I set the adr “off” with the command “mac set adr off” I see that adr is disabled. When I send a confirmed uplink and recheck the adr ![adr|690x401]returns “on”.
Is it a normal behavior?
How can I permanently disable the adr?

It’s a bug at Microchip modules (we’ve experienced it with RN2903 module). It’s been reported for long time, yet there’s been no new firmware fixing it yet. Check also this discussion:
