Pmod BLE: Bluetooth Low Energy Interface - Docs Point to wrong module?

Question

I'm very interested in evaluating the Pmod BLE: Bluetooth Low Energy Interface, however, the documentation has me very perplexed.

All documentation lists the module as RN4870.

All pictures of the PMOD show a RN4871.

What gives?

Hi @ajacks504,

Sorry for the delay. The  RN4871 is the correct part number. I believe you can look here for IC info. We will update our documentation next week when our content team will be back in. Thank you for pointing this out to us.

cheers,

Jon

The one I ordered & received indeed shows RN4871 on the label.

To Digilent (sorry to thread-jack):

What firmware version is loaded on the modules (this significantly impacts the features) ?

Is Data Length Extension supported, and if so to what length (I couldn't find the parameter listed in any of the documentation)?

Hi @Pseudonym1,

We do not know which version of firmware is shipped to us. We do not update the firmware on the RN4871 in the manufacturing test. You can get the firmware version from your Pmod BLE with Sending the “V” command. It will display the firmware info. You can also update the firmware by connecting the PmodBLE to your PC via UART and using the Microchip’s firmware update tool. I do not believe we implemented support for Data Length Extension.

thank you,

Jon

Thanks for the replies.

Bought 2 from Mouser yesterday, can confirm that both have v1.18.3

CMD> RN4871 V1.18.3 4/14/2016 (c)Microchip Technology Inc

Seems like a safe bet that recent Mouser stock of the PMOD is 1.18 if you hurry - can be upgraded pretty easy, see Appendix A of the eval user gude.

EDIT:  Whoops, had 2 connected, wrong COM port!  V1.18 it is.
