Adverting and connection interval

Hi Everyone,

I doing a project where i will be powering my BLE module for  a very short time. i am looking for ways to cut my current consumption and on time. 

1. I know that the slave has to advertise before a connection can be made. But what about if the master knows the slaves address and wants to make a direct connection without the slave advertising. is that possible?

2. I am using the Blueradios module and with that you can stream data when the master and slave are connected. Also i am sending packets from my custom made application through the uart for the slave to send me a packet.  I noticed that a when i increased the connection event time, even though i keep on sending packets , they are not received at the slave end for a while(10-15sec), even though the maximum connection interval is 4sec.  Any help??

3. Does anyone have an idea if bluetooth is suited for such an application. The slave will be powered for a maximum of 300msec.?

  • 1. Even if master knows slave, slave device has to advertise for master to connect to itself.

    2. I don't understand this much. But have you checked that the connection interval is withing supported range?

    3. Some more detail is required to understand your project requirement to make comment on this.
