Hello Kamesh,

You cannot increase the number of channels on the RAK11720 (or any end node).
IN865 is setup to use 3 default channels for the network join.
Once the device has joined the network server, the network server will inform the end node about the additional channels that the device can use.

You have to setup the additional channels in our LoRaWAN server.

so there is no need to change anything on the node side.
only need to change in the Gateway and the network server.
i am using Chirpstack is there any way to add the channels.

You do not need to change anything in the node.

For Chirpstack you have to add the additional channels in the region toml file of Chirpstack.

I don’t have a guide for IN865. You might get help from the Chirpstack forum.

For my regions I had to add the channels in region_as923_3.toml:

    # Below is the common set of extra channels. Please make sure that these
    # channels are also supported by the gateways.
