It's OK now by increasing the attribute table size and then change the IRAM1 on the Keil. Thanks

You don't increase the attribute table size by only increasing the amount of RAM reserved by the SoftDevice, you need to tell the SoftDevice what size you want the attribute table to be. Something like:

ble_cfg_t ble_cfg;
memset(&ble_cfg, 0x00, sizeof(ble_cfg));
ble_cfg.gatts_cfg.attr_tab_size.attr_tab_size = 2000;
err_code = sd_ble_cfg_set(BLE_GATTS_CFG_ATTR_TAB_SIZE, &ble_cfg, ram_start);
APP_ERROR_CHECK(err_code);

This is usually added in ble_stack_init(). If this doens't work, I think you will have to upload your complete project or tell us how to reproduce this error.

Yes, I have tried to increase the attribute table size in the Keil->IRAM1. Also I have tried to use BLE_GATTS_VLOC_USER instead of BLE_GATTS_VLOC_STACK for the characteristic which make the error. Is there any other idear?

Have you tried to increase the attribute table size? Or maybe you can use BLE_GATTS_VLOC_USER instead of BLE_GATTS_VLOC_STACK?

Where are you setting the MTU?

Maybe this example is useful?
