Hello,

Has anyone attempted or had any success in creating a repeater or range extender using the CC2540?

There was one post that said the BLE Stack didn't support that function, but you should be able to retransmit incoming signals through the radio.

Thanks,

    You can start with the CC2530-CC2591EM ref design and replace the CC2530 with a CC2540 and the CC2591 with a CC2590.

    We are in the works of putting together a CC2541-CC2590 Ref Design to be released in the Q3. There will also be BLE stack support for the same in a later stack release.

    Hi Chatto,

    I just wanted to follow-up to see if 'CC2540-CC2590' ref design is out (I searched on 'ti.com', but couldn't find a link, only '2530-2591 ref design' is available).

    Does the BLE stack support repeater capability mow?

    Please let me know.

    Thank you.

    I am trying the BLE stack 1.4.0 with extend range. Application Note AN120 Using CC2590 Front End with CC2541 swra422.pdf

    Is Power Saving Mode must be switch off in order to call the HCI_EXT_ExtendRFRangeCmd function?

    Can CC2591 work with CC2540/CC2541?

    CC2591 gives maximum 22dBm output power whereas CC2590 has maximum of 12dBm.

    It is difficult to find CC2541-CC2590 Ref Design and BLE stack support. Is it released yet?

    Sorry I am totally new to CC25xx. I just got a new enquiry from my customer.

    If I add CC2591 (RF Power Amplifier) to the CC2540/41 BLE reference design, do I have to modify the CC2540/41 ref code/profile stack? Do I have to apply for BQB if CC2591 is added?

    Hi,

    The CC2590 is supported by the BLE stack and you can find more information in the Vendor Specific HCI guide that is included with the stack installer. Have a look at the HCI_EXT_ExtendRfRangeCmd and note that specific pins are used.

    It may need that you will have to re-qualify the PHY layer, so contact a test house for comment on that. Also note that that maximum output power for a BLE device is 10dBm

    Best Regards
