Data Length Extension #ble #nrf52832 #nrf52840 #nrf52

I am trying to enable data length extensions in a connection but am limited to the std 20 payload bytes.
I have a Nordic PCA10040 (nRF52832) running Zephyr v1.14rc1 as a central connected to a Laird BL654 module.  Both devices have what I believe to be DLE enabled.
On the Zephyr side I have enabled:
CONFIG_BT_PHY_UPDATE=y
CONFIG_BT_DATA_LEN_UPDATE=y
CONFIG_BT_CTLR_DATA_LENGTH=y
CONFIG_BT_CTLR_DATA_LENGTH_MAX=251
CONFIG_BT_CTLR_PHY=y
On the BL654 side, the startup flags are set to enable 2M PHY and DLE.
Haven't found a lot of info (other than it should be enabled in the BT stack) or a working sample.  Any help/insight is appreciated.
