after removing the below code,i can receive the gatt data...

can you explain the suituation

CONFIG_BT_HCI_TX_STACK_SIZE_WITH_PROMPT=y

CONFIG_BT_HCI_TX_STACK_SIZE=640

CONFIG_MAIN_STACK_SIZE=4096

i just increased the mtu size..after that only iam facing the above error

CONFIG_BT_USER_DATA_LEN_UPDATE=y
CONFIG_BT_CTLR_DATA_LENGTH_MAX=251
CONFIG_BT_BUF_ACL_RX_SIZE=251
CONFIG_BT_BUF_ACL_TX_SIZE=251

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.

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?

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

Einar Thorsrud — Tue, 10 Dec 2024 13:57:27 GMT

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?
