Device reset when calling sd_ble_uuid_vs_add second time

[George Leung]

I am using nRF5_SDK_11.0.0-2.alpha_bc3f6a0 with PCA10040 and GCC. I am working on the ble hrs with DFU example. I have modify the hrs to my custom service with a 128bit service UUID. I have call sd_ble_uuid_vs_add 2 times, first one is for my custom service init and the second one is in ble_dfu_init. On the second time, it will return NRF_ERROR_NO_MEM and cause the device reset. If I do not include the DFU service or do not include my custom service, it will working fine. Is there any solution for that?

ble_hrs.c

ble_hrs.h

I have try to set the ble_enable_params.gatts_enable_params.attr_tab_size to 0x680 in ble_stack_init of main.c. But I don't know how to set the IRAM1 as describe in the link. If I set the attr_tab_size larger, the softdevice_enable will return error 12, NRF_ERROR_DATA_SIZE. Anyway, I still get NRF_ERROR_NO_MEM when I call the sd_ble_uuid_vs_add in DFU init

Which SoftDevice are you using?

s132_nrf52_2.0.0-7.alpha_softdevice

The default RAM settings in the ble_app_hrs/pca100040/s132_with_dfu is

IRAM1 Start: 0x20001F00  Size: 0x6100

if you increase the BLE_GATTS_ATTR_TAB_SIZE_DEFAULT the correct settings are

IRAM1 Start: 0x20001F00 + BLE_GATTS_ATTR_TAB_SIZE_DEFAULT  
IRAM1 Size: 0x6100 - BLE_GATTS_ATTR_TAB_SIZE_DEFAULT

Thus in your case the correct settings should be:

IRAM1 Start: 0x20002580  Size: 0x5A80
