When you say 'handsfree' are you referring to HFP? What are you using BLE for?
Have you read this article? CYW20706 – BLE Low Power Beacon
You could use the wiced_sleep_config() API to reduce power consumption but if a applicaiton timer is running always, then I don't think there will be any power reduction.
You should be looking at reducing power by changing Tx power or intervals or slave latency (for BLE).
Thank you for your reply.
yes, HFP is right.
And BLE uses several services(GATT, Serial GATT, ANCS, etc) to communicate with the smartphone app.
I know the article.
I don't expect to use wiced_sleep_config() API to reduce power consumption,
My application has several periodic timers
So I asked if there was any other way, especially in hfp.
There is nothing much you could do to reduce power consumption in an Audio application such as HFP.
You could maybe reduce the Tx power. Apart from this, I cannot think of any ways to reduce the current consumption.
Thank you, yssu.
