Hello Hung,

Thanks a lot for the answer,the problem is that as you said the p_app_ram_base is the RAM needed for the software. and if call the buttonless function, should init the fs_init() first. if not, it return NRF_ERROR_INTERNAL.

Have you check what is the RAM memorey softdevice request ? You can get the information about the RAM needed for softdevice when calling sd_ble_enable() the return value of the p_app_ram_base is the RAM needed for the softdevice.

If you still have problem, please zip your project so we can test here.

I have tried vs_uuid_count = 4 event = 5, but failed. the 0x20002B80 is a test and didn't work. I 'm not sure what the problems cause the error NRF_ERROR_NO_MEM or NRF_ERROR_INTERNAL. please help me solve this problem. Thanks in advance.

Have you tried vs_uuid_count = 3 ? Also would the 0x20002B80 is what the softdevice request ?

Hello Hung Bui,

the exactly place return NRF_ERROR_NO_MEM is in the line 175 of ble_dfu.c

err_code = sd_ble_uuid_vs_add(&nus_base_uuid, &p_dfu->uuid_type); VERIFY_SUCCESS(err_code);

and below is my setting of the project

IROM1: start: 0x1B000 size: 0x25000 IRAM1: start: 0x20002B80 size: 0x5480

I have also changed the IRAM1 start address and size, but it didn't work yet.

Hi,

Please check and tell which exactly the function returns NRF_ERROR_NO_MEM. Have you updated the RAM setting in your project to give enough RAM for the softdevice (IRAM1 setting). You can have a look at the answer from Bjørn here.
