How Slave Latency affects the data sending process of a slave device?

[xvhongpeng]

Dear friends,

         If i set the conection interval=100ms and the slave latency=1, the slave will wake up every 200ms. If the slave has data to send, it will still wake up every 100ms. However,  "If the slave has data to send, it will wake up immediately", what does "immediately" mean? For example, if data come at the time when the slave just goes to sleep, it will wake up immediately to send data? or it has to wait 100ms until the next connection event comes?

        regards.

Hi,

 

In your case, the slave will wake up and send in the "nearest 100 ms slot", so the worst-case latency from you uploading the data to the stack to it being sent on-air is 100 ms.

Slave latency will not wake up immediately and send on-air, it will conform to the connection parameters set for your bluetooth link.

 

Best regards,

Håkon
