Peripheral initiates disconnection

[Shay Ohayon]

How can a peripheral initiate a disconnection after it has connected to a central?

Update: I use mbed.

[RK]

sd_ble_gap_disconnect()

[Shay Ohayon]

Is this implemented in mbed?

To complete the correct answer given by @rols:

Mbed use internally SDK/SoftDevice functions provided by Nordic. To disconnect, you can use the following method of the nRF5xGap class:

ble_error_t nRF5xGap::disconnect(Handle_t connectionHandle, DisconnectionReason_t reason)

Which uses the sd_ble_gap_disconnect() function internally, see the source here on Github.
