I increased

//#define NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE 1408
#define NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE 2000

to 2000. And now works without fall. It good. But wich size should set for correct work?

2000- is it normal or this is big size?

Hi!

I tryed increased NRF_SDH_BLE_VS_UUID_COUNT by 2 and 3 without success.

I have next services:

nus_init();
sls_init();
tis_init();
hids_init();

First 3 works fine. When added hids_init(); , project fall with ERROR 4. Also possible leave only hids_init(); and delete

nus_init();
sls_init();
tis_init();

also works fine.

I understand that need increase memory but I can't understand how to make it correct.

How big are these services? Many characteristics?

Perhaps you need to increase the size of you attribute table? NRF_SDH_BLE_VS_UUID_COUNT only counts for Vendor Specific UUIDs. Do you use those? Or only Bluetooth SIG defined UUIDs?

typedef struct
{
  uint32_t attr_tab_size; /**< Attribute table size. Default is @ref BLE_GATTS_ATTR_TAB_SIZE_DEFAULT, minimum is @ref BLE_GATTS_ATTR_TAB_SIZE_MIN. */
} ble_gatts_cfg_attr_tab_size_t;
