CC2630: Save data in NV memory

Philipp Sperber

Part Number: CC2630
Other Parts Discussed in Thread: Z-STACK,

Hi,

i'm using the CC2630 with the IAR Workbench and the Z-Stack™ Home 1.2.2a. I need to save sensor data to NV memory. As discussed in other threads the osal is not accesible for the application so i need to use the zcl_port functionality.

I initialize the item then write and after a power cycle read:

zclport_initializeNVItem(0x2FE,0x0001, sizeof(uint16_t),NULL);

uint16_t luxValueFromSensor = 500;
zclport_writeNV(0x2FE,0x0001,0, sizeof(uint16_t),&luxValueFromSensor); 

zclport_readNV(0x2FE,0x0001,0, sizeof(uint16_t), &zisMeasuredValue);

While init and write return NV_ITEM_UNINIT, the read returns SUCCESS but i always read 0.

Hi Philipp,

The person who can answer this is out on vacation today and will be back in office tomorrow. I apologize for the delay.

You should use NV ID after 0x0100. You can refer to discussions in e2e.ti.com/.../2096439

Hi Yikai,

thanks for the reply. I changed the NV ID to 0x0281 as you suggested in http://e2e.ti.com/support/wireless_connectivity/zigbee_6lowpan_802-15-4_mac/f/158/p/667400/2456846#pi319568=2 but that didnt change anything. I still get 0 when reading.

Regards Philipp

Try to use the following code:

zclport_writeNV(0x2FE,0,0, sizeof(uint16_t),&luxValueFromSensor);

zclport_readNV(0x2FE,0,0, sizeof(uint16_t), &zisMeasuredValue);

Unfortunately that didnt help. I also tried initializing with sub id 0 too.

If you try the following codes, does it work?

uint8 luxValueFromSensor = 0x78;
zclport_writeNV(0x2FE,0,0, 1,&luxValueFromSensor);

zclport_readNV(0x2FE,0,0, 1, &zisMeasuredValue);

No that did not work either. I initialized like this:

zclport_initializeNVItem(0x2FE,0,1,NULL);

May I know where you call those NV write/read API?

Test this at the end of your app init function:

uint8 luxValueFromSensor = 5;
uint8 zisMeasuredValue;

// Init NV item
zclport_initializeNVItem(0x2FE,0,1,NULL);

// Read 0xFF
zclport_readNV(0x2FE,0,0, 1, &zisMeasuredValue);

// Write 0x05
zclport_writeNV(0x2FE,0,0, 1,&luxValueFromSensor);

// Read 0x05
zclport_readNV(0x2FE,0,0, 1, &zisMeasuredValue);

Try this in a fresh new application, I didn't have to configure anything on the project to make it work.

Thanky ou very much YiKai! Putting it in the task with the right context solved that problem.
