fix(nimble): Updated BLE Phy example
The existing example has some issues which are now fixed. 1. Original example had legacy_pdu set which was not causing the PHY to actually change. Fixed this 2. Added a way to initiate connection directly on 2M or Coded Phy.

## 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.
