    摘要： The present invention discloses a role exchange method for Bluetooth system. It comprises the steps of: a first slave asking role exchange and transmitting a FHS packet to a first master at a first time point t1; the first master exchanging as a second slave at the second time point t2; the first slave re-transmitting a plurality of FHS packet; and the first slave exchanging as a second master automatically. The role exchange method according to the present invention can solve the failure problem of role exchange procedure due to the noise in the conventional Bluetooth scheme.

    摘要： A channel quality evaluation method applicable to Bluetooth wireless network sends a first channel detecting format packet from the Bluetooth master to the Bluetooth slave. The master verifies if the slave recognizes the first channel detecting format packet from the response from the slave. If the Bluetooth slave does not recognize the first format detecting packet, the Bluetooth master will send a second channel detecting format packet. The error rate is to be calculated according to the response from the Bluetooth slave to obtain an estimate of the channel qualify. This method obtains the channel quality efficiently and does not interfere with the normal operation of the Bluetooth devices.
