LAUNCHXL-CC26X2R1: Clean the nvram setting when pressed the reset button

Lawrence Lin

Hi TI team,

I knew the information of Zigbee will be saved into NVRAM if my End-Device(switch) joined my Coordinator(light) previously.

I want to implement a function is that when I press the reset button, I can clean the NVRAM setting.

Could you teach me which API I can use for cleaning the NVRAM setting?

I saw a reset(BPRST) pin on CC2652 but I could not find any source code about it. Could you also teach me how to trigger reset button in source code?

Thanks

I think you can 0x3 NV_ID for this.
If you write in ID_ItEM (0x3) 0x2 And restart- it will be Clear_State. If 0x1 - and Restart it will be reset to default

Hi Pavel,
I saw a reset(BPRST) pin on CC2652 but I could not find any source code about it.
Could you also teach me how to trigger reset button in source code? I want to find some source code for this reset(BPRST), first.
Thanks

Where do you see BPRST?

Hi Pavel,
On my LAUNCHPAD board of CC2652. And you also can refer to the Pin Diagram and Signal Descriptions in datasheet(www.ti.com/.../swrs207a.pdf).

This BPRST is a RESET_N(35) in this datasheet.
Thanks

I suppose you call API bdb_resetLocalAction to to factory reset.

It is hrdware reset.
When you press this buttom you MCU will be reset and start program again.

Hi Pavel,
I do not need to modify my code if I want to use this button to be a reset. It will automatically do factory reset??
Thanks

No! This button only restart you MCU. But all network state will be restore from NV_ROM. If you always factory reset your device (I think it is'nt good idea) you must add same code in you initialization. It is write 0x2 (or 0x3) in the ZCD_NV_STARTUP_OPTION

0x2 - Clear_state

0x1 - Factory_Reset

0x3 = Clear_state | Factory_Reset
