Part Number: CC2538

Tool/software: TI-RTOS

We have designed following system

AM437x communicates with CC2538 over uart.CC2538 act as co-ordinator and AM437x act as gateway.

We are using ZSTACK 1.2.2 with IAR workbench.

We save all configuration in config.txt file. This file is stored on sd card of am437x from where it boots.

We are planning following activity:=

1.Save PAN ID of CC2538 in config.txt.

2.During the power on am437 read the config.txt and pass the value of PAN-ID to C C2538

3.CC2538 read the value of PAN-ID and change its PAN ID.

I want to understand following:

Is it posible to change PAN-ID of CC2538 during runtime?If yes please suggest method of doing this in runtime?
What will be effect of change of PAN ID of co-ordinator on connected end devices during runtime ? Will they automatically join to co-ordiantor?

1. I should be able to change PANID at run time but it means coordinator forms a new network.
2. Device won’t be able to rejoin once you change PANID.

Hi YiKai,

Thanks for quick reply.

1. I should be able to change PANID at run time but it means coordinator forms a new network.

please mention way to change PANID during runtime.

2. Device won’t be able to rejoin once you change PANID.

is there any method by which end device will rejoin to co-ordinator once we change the PANID?

1. Do you use ZNP? If so, you can just do factory reset to change PANID.
2. I don’t think there’s a good way to achieve this.

By the way, why do you need to change PANID dynamically? It’s unusual to do so.
