erase NVRAM in the nrf dongle to reset the network parameters

[Manju_rn]

I was just thinking whether the below set of lines could be a solution to the problem faced in this case https://devzone.nordicsemi.com/f/nordic-q-a/83358/light_bulb-example-for-52840-dongle where the zigbee network parameters were not clearing during each flash. The suggestion of flashing clear_flash.hex before each application flash works, but wondering if the below would work and the clear_flash may not be required?

/* Do not erase NVRAM to save the network parameters after device reboot or
 * power-off. NOTE: If this option is set to ZB_TRUE then do full device erase
 * for all network devices before running other samples.
 */
#define ERASE_PERSISTENT_CONFIG    ZB_TRUE

void main(void)
{
    ...
	zigbee_erase_persistent_storage(ERASE_PERSISTENT_CONFIG); // Call before enabling the zigbee enable
	...
}

Hi,

Setting erase persistent storage with zigbee_erase_persistent_storage(ZB_TRUE) will make it so that the network data is erased on application startup, so it should be erased when the device starts up after flashing.

Best regards,

So this means that I would not have to write the dongle with clear_flash.hex before I write any application code?  As explained earlier, I currently have to do this (without the above persistent code) each time since the zigbee network settings are persisted

Hi,

That is correct, it should be enough to erase it with zigbee_erase_persistent_storage().

Best regards,
