Bluetooth Connection establishment maximum time, if connection time exceeds this value, the connection
establishment fails, ESP_GATTC_OPEN_EVT or ESP_GATTS_OPEN_EVT is triggered.
config BT_MAX_DEVICE_NAME_LEN
int "length of bluetooth device name"

range 32 248
default 32
help
Bluetooth Device name length shall be no larger than 248 octets, If the broadcast data cannot contain
the complete device name, then only the shortname will be displayed, the rest parts that can't fit in
will be truncated.
config BT_BLE_RPA_SUPPORTED
bool "Update RPA to Controller"
