Cannot read/write in nvs when gatt,Bt is active?

[lara]

Hi,

iam trying to write the data in nvs which i give input through GATT.i  can read and write in nvs when not using gatt,BT.

I have 2 codes,1 is working but without GATT and BT.

another 1 is not working with GATT and BT.

while initialise the nvs i got the following error,

[00:00:00.059,661] <err> flash_nrf: invalid address: 0x00080ff8:8
Error: Failed to write JSON data to NVS, rc=-22

in wrking code there is a separate partition for nvs,but in non working code there is not.i use the same build config for both the codes.is it because of enabling the GATT and BT?Please someone guide

[Einar Thorsrud]

Hi,

There is no fundamental issue with wiring to flash and using BLE in the same project. As you use NVS I assume you write to the NVS partition, and that is missing in the non-working partitions.yml. Did you use a static partition layout here, or was it not added? Do you get any information about it in the build log? Can you share that?

yes,I use/add pm_static.yml..my build log

Hi,

Thank you. I wonder why the settings_storage region is not part of the Bleutooth application in this case. Can you send the generated .config for both your non-working (bluetooth) application and the working one? Or perhaps the full build folders for both so that I can have a look?

Hi,

Looking at the configs I notice that the non-working does not have CONFIG_PM_PARTITION_SIZE_NVS_STORAGE defined. Is the issue resolve by adding CONFIG_PM_PARTITION_SIZE_NVS_STORAGE=0x6000 to your prj.conf? This is skipped by default when using settings.
