## Intiating connection on 2M / Coded Phy
This example also provides a way to initiate connection directly on 2M / Coded PHY. For this, set the peripheral device address in EXAMPLE_PEER_ADDR setting via menuconfig. Also example needs to be modified to use the PHY that user needs to update.
In main.c file, in blecent_on_sync function, set the s_current_phy to the intended phy.
To create direct connection on 2M, set the s_current_phy to BLE_HCI_LE_PHY_2M_PREF_MASK.
To create direct connection on Coded Phy, set the s_current_phy to BLE_HCI_LE_PHY_CODED_PREF_MASK
Recompile application and flash the image.
Note: For this setting to work ,the remote device too should be advertising with either 2M auxillary phy OR Coded phy.
Also, since this mode initiates direct connection, ensure that peripheral is already advertising, before executing this application.

## Accepting connection directly on 2M / Coded Phy
The example can also be configured to advertise directly on 2M auxillary PHY or CODED PHY
In main.c file, in bleprph_on_sync function, set the s_current_phy to the intended phy.
To advertise, using 2M Phy, set the s_current_phy to BLE_HCI_LE_PHY_2M_PREF_MASK.
To advertise, using Coded Phy, set the s_current_phy to BLE_HCI_LE_PHY_CODED_PREF_MASK
Recompile application and flash the image.
Since , in this mode, the central will initiate direct connection, ensure that peripheral is already advertising, before initiating connection from the central device.
