nrf5340 bt_le_ext_adv_create error -11 BT_DEV_READY

[billywalton]

Hi,

I have a nrf5340, on a custom board

I call bt_enable(NULL) without error, but when I try and cretae an advertisment set, calling bt_le_ext_adv_create returns error -11, it bombs on the BT_DEV_READY check.

What could be stopping BT_DEV_READY from being set?

my conf

CONFIG_BT=y
CONFIG_BT_DEBUG_LOG=y
CONFIG_BT_PERIPHERAL=y

CONFIG_BT_EXT_ADV=y
CONFIG_BT_EXT_ADV_MAX_ADV_SET=2
CONFIG_BT_USER_PHY_UPDATE=y

Many thanks

error -11 seems to be defined as

#define EAGAIN 11       /**< No more contexts */

How to increase 'contexts'?
