Change IEEE address on SMHB radio

Change IEEE Address on EFR32

1. Stop all applications using the EFR32 SoC, including internal apps on SMHUB (e.g. Zigbee2MQTT) or any external applications if the EFR32 is used remotely (for example, Zigbee2MQTT running on another server).

2. Open SMHUB-OS Web Terminal.

3. Run the command below (replace the IEEE address 00124b1209d43d4f if needed):
   SMHUB Nano Mg24:
   universal-silabs-flasher --device /dev/ttyS1 write-ieee --ieee 00124b1209d43d4f
   
   SMHUB Essential/Premium:
   universal-silabs-flasher --device /dev/ttyS2 write-ieee --ieee 00124b1209d43d4f

4. Wait until the EFR32 SoC is detected and the IEEE address is written.

5. Confirm the operation by checking the output.
   

   INFO Probing ApplicationType.EZSP at 115200 baud
   INFO Detected ApplicationType.EZSP, version: 8.0.2.0
   INFO Current device IEEE: ec:f6:4c:ae:fe:21:ae:12
   INFO Wrote new device IEEE: 00:12:4b:12:09:d4:3d:4f

   

6. Should work without a restart, but if not, please reboot with a power cycle (e.g., power off from the power and then power it on).
