I'm getting the warning about CONFIG_BT_CTLR, but I've gone through and changed to HAS_BT_CTLR. I do have the following:
# Maximum Transmission Unit config
CONFIG_BT_GATT_AUTO_UPDATE_MTU=y
CONFIG_BT_CTLR_DATA_LENGTH_MAX=251
CONFIG_BT_BUF_ACL_RX_SIZE=251
CONFIG_BT_BUF_ACL_TX_SIZE=251
CONFIG_BT_L2CAP_TX_MTU=247
I suspect that CONFIG_BT_CTLR_DATA_LENGTH_MAX might be turning it on? But I can't figure out what to replace it with--CONFIG_BT_CTLR_DATA_LENGTH_MAX isn't giving a deprecated notice.
Any ideas?
