LPSTK-CC1352R: Sensor Address Changes after Disassociation?

Part Number: LPSTK-CC1352R
Other Parts Discussed in Thread: CC1352R

Hi,

I have 2 LPSTK-CC1352R sensor connected to 1 CC1352R Launchpad collector. After disassociation of 2 sensor the sensor address changes. Example before the sensor address is 0x0001 and 0x0003, after disassociation the sensor address now becomes 0x0003 and 0x0004. It will be hard to keep track of sensor nodes if the address keeps changing especially if my application is IOT. Is this normal? Can I make it to not change sensor address after disassociation?

Hi kel,

Rejoining devices should maintain the same address but disassociation will cause the collector to delete all previous device information and not re-use the previous address. So on a new join the previously-disassociated device will be assigned a new short address. You can maintain a record of the extended addresses in your application to resolve the issue.
