NRF5340 PHY Configuration

[MSDEV]

We're working with the NRF5340 PDK, and it's a pretty big library change from the old SDK. So far I've been unable to find out where to configure the bluetooth PHY and link layer in Zephyr. Can I get some assistance on maximizing the throughput of the NRF53?

Hi,

Check out: \nrf\samples\bluetooth\throughput

Best regards,

That's exactly the sample I'm running. The issue is I can't find variables in the menuconfig that correspond to those settings, and no code I can find uses the zephyr api to set them. 

Parameter	Value
ATT_MTU size	247 bytes
Data length	251 bytes
Connection interval	320 units (400 ms)
PHY data rate	2 Ms/s

Could you let me know what the config variables for each of these is?

If it's not in Bluetooth->"L2CAP Options" or "ATT and GATT Options", then it's in the prj.conf file. 

-edit: Found these configs in proj.conf;

CONFIG_BT_L2CAP_TX_MTU=247

CONFIG_BT_CTLR_DATA_LENGTH_MAX=251

CONFIG_BT_CTLR_PHY_2M=y

Connection parameters can be found in: kconfig/menuconfig->Bluetooth->ATT and GATT Options->Configure peripheral preferred connection parameters.
