The value I listed is the default value for the example. The RAM usage will increase if you add more services, characteristics, etc. If you enable logging, the RAM size required should be printed on the terminal. E.g. :

**SDH:INFO:sd_ble_enable: RAM START at 0x20002168
SDH:WARNING:sd_ble_enable: app_ram_base should be adjusted to 0x20002128
SDH:WARNING:ram size should be adjusted to 0xded8**

Make sure that you have #define NRF_LOG_BACKEND_SERIAL_USES_UART 1 and #define NRF_LOG_ENABLED 1 in sdk_config.h if you are printing over UART.

Thank you for your answers, I changed de IRAM and it’s still not working, as you suggest I’ll try to download a new copy of the SDK. Where did you find information about the use of RAM with s132? (I can find easily information about ROM but that's harder for RAM). Thank’s

Ok, the IRAM looks wrong. It should be start: 0x200025f8 with size: 0xda08. If this doesen't fix the issue, download a new copy of SDK 13 from here.

My mistake. I’m using nrf52832, sorry for that, I change the tag right now!

I see that you have nrf52840 in the tag, if that is the case you need use the S140 Softdevice, and the project named ble_app_uart_pca10056_s140
