It is standby to be not in suspend mode, for example, when carrying out service interaction with main equipment from equipment, then it can be with end operation process.
In practical applications, can by obtain last time receive from the time slot of the data packet that equipment is sent with it is current when
Interval duration between gap judges whether be in suspend mode from equipment.When being spaced duration less than preset duration, then determine
Suspend mode is currently not yet in from equipment；When duration reaches preset duration when interval, that is, it can determine that and be currently at not from equipment
Sleep mode.
In embodiments of the present invention, main equipment end can send connection thing to from equipment according to preset period timing of giving out a contract for a project
Part.When main equipment detects that continuous N number of period of giving out a contract for a project does not receive from the reply data that equipment is fed back, determine from equipment
In suspend mode.Wherein, N and the product in period of giving out a contract for a project are preset duration.
In practical applications, the value range of N can be set according to the actual situation.In an embodiment of the present invention, N is set
=10, i.e., when not receiving from the reply data that equipment is fed back in main equipment continuous 10 periods of giving out a contract for a project, that is, determine from equipment
In suspend mode.
In an embodiment of the present invention, it is received according to current time corresponding clock count value and the last time from setting
The corresponding clock count value of reply data packet that preparation is sent, to judge whether receiving the corresponding response of a upper connection event
Data packet.
Current time corresponding clock count value is Current_clks, and the last time receives the response sent from equipment
The corresponding clock count value of data packet is last_clks.The difference that Current_clks and last_clks are subtracted each other, and will be obtained
Value is divided by ConnInterval, when obtained quotient is greater than 1, namely when (Current_clks-last_clks)/
When ConnInterval > 1, then determine main equipment it is upper once to opposite equip. send connection event after, do not receive from
The reply data of equipment feedback.
Step S102 gives out a contract for a project the period every M connection event, continuous T time to it is described from equipment send connection event and
Monitor the operation of the reply data packet sent from equipment.
By existing Bluetooth protocol it is found that when a slave is in the park mode, every latency × ConnInterval to
Main equipment sends a reply data packet.But when from suspend mode normal industry is switched to from equipment due to unpredictable
Be engaged in interactive mode, to ensure being normally carried out for service interaction, main equipment can not every latency × ConnInterval just to from
Equipment sends a connection event.
In embodiments of the present invention, when detect be in suspend mode from equipment after, can be sent every M connection event
Period, then continuous T connection event give out a contract for a project the period to from equipment send connection event and monitor whether receive from equipment send out
The reply data packet sent, M, N are positive integer.
That is, latency connection event period of giving out a contract for a project is divided into latency/ (T+M) a period, i.e., each
Period includes that T+M connection event is given out a contract for a project the period, wherein preceding M connection event is given out a contract for a project, the period is not attached the hair of event
It send, is only attached the transmission of event in rear T connection event period of giving out a contract for a project.
For example, latency=100, T=4, M=6, then 100 connection events period of giving out a contract for a project is divided into 100/10=10
A period, each period include that 10 connection events are given out a contract for a project the period, wherein preceding 6 connection events are given out a contract for a project, the period is not attached
The transmission of event is only attached the transmission of event in rear 4 connection events period of giving out a contract for a project.
In embodiments of the present invention, T and M can be set according to actual application scenarios.For example, T=can be set
4, M=6；T=5, M=5 etc. can also be set.
Give out a contract for a project the period to during sending connection event from equipment, when receiving from equipment in continuous T connection event
When the reply data packet of transmission, it is possible to determine that normal service interaction mode currently has been switched to from suspend mode from equipment,
S101 is re-execute the steps to rejudge from whether equipment is in suspend mode.
In existing Bluetooth protocol, main set is not received within latency periods of giving out a contract for a project when detecting from equipment
After the connection event that preparation is sent, it is both needed to monitor whether main equipment sends connection thing in each Connection Time point later from equipment
Part, to ensure the normal work of link.
In the prior art, when a slave is in the park mode, it is received successively every latency × ConnInterval
The connection event data packet that main equipment is sent.And since main equipment can not be known from when equipment can switch to just from suspend mode
Normal business model, therefore, main equipment with preset connection event give out a contract for a project the period timing to from equipment send connection event, with prison
Accept whether equipment initiates business.However, main equipment continually sends data packet to from equipment in each connection event point, lead
Cause the waste of time interval resource.
And in embodiments of the present invention, when a slave is in the park mode, main equipment is given out a contract for a project week every M connection event
Phase executes T times to the operation for sending connection event from equipment, i.e., gives out a contract for a project in the period in (T+M) a connection event, wherein M connection
Event give out a contract for a project the period not to from equipment send connection event, only T connection event give out a contract for a project the period to from equipment send connection
Time, so as to save time interval resource.
For example, T=4, M=6, latency=100, then in the prior art, when a slave is in the park mode, main
Equipment, which receives, once need to send 100 connection events from the reply data that equipment is fed back.And in embodiments of the present invention, when from
When equipment is in suspend mode, main equipment, which receives, successively need to only send 40 connection events from the reply data that equipment is fed back,
Therefore the bluetooth equipment data transmission method provided in the embodiment of the present invention can be effectively saved time interval resource.
