If there is not sufficient RAM for the softdevice you will receive an error and in the log you will find which RAM size you need to modify to. Have a look at nrf_sdh_ble_enable() function inside nrf_sdh_ble.c

Hi, thank you for your reply,

how to make the link between the NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE and the RAM_START ??

Actually i have:

FLASH_PH_START=0x0

FLASH_PH_SIZE=0x80000

RAM_PH_START=0x20000000

RAM_PH_SIZE=0x10000

FLASH_START=0x26000

FLASH_SIZE=0x5a000

RAM_START=0x20002a98

RAM_SIZE=0xd568

i took that from the ble_app_uart example configuration but i don’t really understand how it works.

Thank you

Hi Arthur,

You would need to increase the NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE in sdk_config.h . Note that when you increase the NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE you would also need to increase the softdevice's allocated memory in project setting (the start address of RAM for application).
