Is there any at command or method to know the link status?

Is there any at command or method to know the link status?
I saw “linkcheckreq” command on the lorawan v1.1 specification.
Is there a RAK module that supports the linkcheckreq command?
Please let me know if there is any command or method to check the link status of the module.
(We are using rak811 module.)
Thanks.

Hi. RAK811 is LoRaWAN 1.0.2 compatible. This will be available when RAK implements the 1.1 specification.

Thank you very much!

Are there any RAK modules that supports v1.1?

For now, no. You can read more here RAK811 upgrade to LoRaWAN 1.1
