Apparatus and method of choosing working frequency points

A computer-implemented method (400) of choosing working Bluetooth frequency points for a Bluetooth receiver operating in a Bluetooth frequency range, comprising:

• dividing entire Bluetooth frequencies of the Bluetooth receiver into Bluetooth frequency classes based on a frequency relationship among Bluetooth channels of the Bluetooth receiver and non-overlapping Wi-Fi channels of an interfering Wi-Fi device operating in a Wi-Fi frequency range within the Bluetooth frequency range, wherein a first Bluetooth frequency class comprises a Bluetooth frequency group including at least a lowest Bluetooth frequency and a highest Bluetooth frequency in the Bluetooth frequency range wherein a second Bluetooth frequency class comprises a Bluetooth frequency group including Bluetooth frequencies higher than the highest frequency in the Wi-Fi frequency range, wherein a third Bluetooth frequency class comprises multiple Bluetooth frequency groups each including Bluetooth frequencies between two adjacent Wi-Fi channels of the Wi-Fi channels, and wherein a fourth Bluetooth frequency class comprises multiple Bluetooth frequency groups each including Bluetooth frequencies covered by one of the Wi-Fi channels;
• determining one or more working Bluetooth frequency groups based on pre-determined requirements, wherein a particular Bluetooth frequency group of a particular Bluetooth frequency class is determined qualified or unqualified as a working Bluetooth frequency group by detecting a predetermined number of qualified or unqualified frequencies in the particular Bluetooth frequency group;
• and
• saving entire working Bluetooth frequencies within the one or more working Bluetooth frequency groups into a channel map table.

A non-transitory computer-readable medium storing instructions that, when executed by one or more computer processors of a Bluetooth receiver (100) operating in a Bluetooth frequency range covering multiple Bluetooth channels, cause the Bluetooth receiver to perform operations comprising:

• dividing Bluetooth frequencies of the Bluetooth receiver into Bluetooth frequency classes based on a frequency relationship among the Bluetooth channels of the Bluetooth receiver and non-overlapping Wi-Fi channels of an interfering Wi-Fi device operating in a Wi-Fi frequency range within the Bluetooth frequency range, wherein a first Bluetooth frequency class comprises a Bluetooth frequency group including at least a lowest Bluetooth frequency and a highest Bluetooth frequency in the Bluetooth frequency range, wherein a second Bluetooth frequency class comprises a Bluetooth frequency group including Bluetooth frequencies higher than a highest frequency in the Wi-Fi frequency range, wherein a third Bluetooth frequency class comprises multiple Bluetooth frequency groups each including Bluetooth frequencies between two adjacent non-overlapping Wi-Fi channels, and wherein a fourth Bluetooth frequency class comprises multiple Bluetooth frequency groups each being covered by one of the Wi-Fi channels;
• determining one or more working Bluetooth frequency groups based on pre-determined requirements, wherein a particular Bluetooth frequency group of a particular Bluetooth frequency class is determined qualified or unqualified as a working Bluetooth frequency group by detecting a predetermined number of qualified or unqualified frequencies in the particular Bluetooth frequency group;
• and
• saving entire working Bluetooth frequencies within the one or more working Bluetooth frequency groups into a channel map table.
