https://test-devzone.nordicsemi.com/f/nordic-q-a/88023/turn-off-bluetooth-of-nrf52832Hello, I&#39;m on the development of a biomedical application using nrf52832 module. Would like to know if the CPU core can be able to isolate itself (ignore all incoming interrupts), turn bluetooth completely off, and occupy only the external sensor overen-USTelligent Community 13 Non-ProductionWed, 18 May 2022 13:52:14 GMThttps://test-devzone.nordicsemi.com/thread/368396?ContentTypeID=1Wed, 18 May 2022 13:52:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:47ddd9f0-5ec5-451c-a550-5d1dcd44c286user14926<p>Hi,</p> <p>You can disable the Softdevice using the&nbsp;<a title="Functions" href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.api.v7.3.0/group___n_r_f___s_d_m___f_u_n_c_t_i_o_n_s.html?cp=4_7_3_1_2_8_2">Softdevice Manager Functions</a>. If the softdevice is disabled, there will be no BLE activity, and you have access to all peripherals and priority levels. If the softdevice is enabled, some priorities and peripherals will be unavailable for the application.
