CC2640R2F: Stay connected between 2 BLE devices

Part Number: CC2640R2F


Hi ,

       I am running BLE Peripheral on one device and BLE Central on the other device .

I want to know is there any data transfer is required to stay connected between BLE Central and peripheral .

Setting Max Connection interval to 4sec and supervision timeout to max .

I will connect from BLE Central device to BLE Peripheral device which kept next to each other .

does it stay connected as long both are nearby ?

if no , what i need to do to stay connected forever .

I want both BLE device should not be doing anything ( sleeping/suspend  state ) , so both consumes very less power and yet both are connected .

Regards

Raghu DP
