CC2640R2F: Configuring device as Bluetooth repeater

Part Number: CC2640R2F
Other Parts Discussed in Thread: CC2640,

Hi,

I'm looking at creating a device to act as a Bluetooth repeater for a wireless network involving a phone and BLE enabled wireless sensor (4.0 & 4.2).  The main goal is to increase the effective range that the phone+repeater could achieve. 

Would using two CC2640 MCUs be the easiest way to implement this? This feels a little brute force and possibly expensive. It would have one MCU with range extender to connect to the remote wireless sensor, and then would have another MCU to connect to the phone which would be closer.

Thanks,

Eric

    Hi, 

    Might be easier visualize with a diagram. But why could not the MCU with range extender be also used to connect to the phone since the CC2640R2F can support two simultaneous connections?

    Best wishes

    Hi Zahid, thanks for getting back to me.

    The wireless sensor and repeater would both be using CC2640R2F alongside the RF range extender. The issue we have now is that the phone can receive the signal from the sensor, but doesn't have a powerful enough radio to transmit data back at that range. We would need a device with better transmit power to relay the communications between the sensor and the phone.

    Would the simultaneous connections still be supported in 4.0?
