Yes, in Nordic's SDKs BLE related interrupts are usually called something_handler. E.g. ble_evt_handler().

Hi Martin,

Can you tell me, BLE sofedevice interrupt name is (_handler)? I used the nRF5_SDK_15.0.0 ble_app_blinky sample code.

Hi,

If you are using BLE you can expect to see distortion like this. The Softdevice does timing critical processing in high priority interrupts that will delay your timer application interrupts. Please refer to the Softdevice Specification: Bluetooth Low Energy Advertiser (Broadcaster) processor usage. As you can see, you can expect tens and hundreds of micro seconds delays when the Softdevice is active.

I have used BLE function, but I don't no how to do.
