I want to explain it as “Master Or Slave”, because this is explained in the Core_v5.2 8.6.5 Role switch There are several occasions when a role switch is used: • A role switch is necessary in order to make a paging device a slave when joining an existing piconet, since by definition the paging device is initially master of a piconet involving the pager (master) and the paged (slave) device. • A role switch is necessary in order for a slave in an existing piconet to set up a new piconet with itself as master and the original piconet master as slave. If the original piconet had more than one slave, then this implies a double role for the original piconet master; it becomes a slave Signed-off-by: wangyouwan <wangyouwan@xxxxxxxxxxxxx> --- monitor/packet.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/monitor/packet.c b/monitor/packet.c index 52d22ab21..b73615509 100644 --- a/monitor/packet.c +++ b/monitor/packet.c @@ -4143,7 +4143,7 @@ static void create_conn_cmd(const void *data, uint8_t size) str = "Stay master"; break; case 0x01: - str = "Allow slave"; + str = "Master Or Slave"; break; default: str = "Reserved"; -- 2.20.1
