Receive a broadcasted packet within 5 sec

[sunil.dhaduk]

Hi,

I want to design one BLE braodcaster and one BLE observer using nRF51822 chip.

What should be the advertising interval time and receiving interval time (with receiving window time) to receive the broadcasted packet within 5 sec without any failure?

It should be power optimized to ensure minimum power consumption.

Hi Shibshab,

Thank you for your valuable reply...

During connection interval, how both devices will be synchronized?

For connection event, one also has to receive other's broadcasted packet.

Please correct me if I am wrong.

They are synchronized using the timing set up in the CONNECT REQUEST packet. The 'observer' will automatically turn on the radio a few microseconds before the 'broadcaster' will transmit its data. Since the two devices are synchronized, it can do this since it knows exactly (within a defined margin) when the packet will arrive.
