    WLAN firmware with BLE

    ShCa_4362486

      Hi,

       

      I  am using i.mx RT 1064 to talk to murata 1MW (CYW43455) module through SDIO. I am running the WLAN firmware provided.

      Is it possible to use BLE at the same time (through HCI over UART)?

       

      As far as I can see, the WLAN firmware does not have source code available, so i cannot edit it to add the BLE functionality.

          Mostly, BT/BLE firmware will be downloaded from UART interface,  and run in another core  , so WLAN firmware can't match your needs.

          A:  yes , wlan and bt can run together.

            Is there source code or example code for the WLAN firmware running through SDIO?

             

            I have integrated the WLAN firmware with the LWIP stack on my host uC (i.mx RT1064). Ideally I would prefer to make minimum changes to WLAN firmware to add in BLE (UART) functionality, but I'm not sure how to achieve this.

                Hi ShCa_4362486,

                 

                The BLE is not functional on i.MX RT 1064 EVK yet that is why the BLE example is not included in the SDK. There was an issue with the BLE example and work is underway to fix the issue.

                 

                You can try using i.MX RT 1060 EVK instead of i.MX RT 1064 EVK. Both have almost the same features. Both Wi-Fi and BLE are functional on i.MX RT 1060 EVK. So if you want both Wi-Fi and BLE functionality, i.MX RT 1060 EVK is a better choice for now.

                 

                I hope this helps you.

                 

                Thanks,

                Puja

                  Thank you for pointing it out, it's very useful as a reference. I do not have the i.mx 1064 EVK yet, but i will test it out when i get it.

                   

                  Will this example work with 1MW(CY43455)?

                   

                  WICED_BLE library in the example appears to contain a firmware file, which is also in the wiced_bt_passthrough example for i.mx rt 1064 EVK example:


                  BCM4343A1_001.002.009.0103.0000_Generic_UART_37_4MHz_wlbga_wiced.hcd


                  Is this file used and needed? If so would it work with 1MW (CY43455)? If not, are there plans to release the equivilent firmware file in the future to support 1MW (CY43455)?

                    1MW is not included in the SDK for any i.MX RT family EVKs yet. Work is going on to include 1MW in the future release.

                     

                    Yes, the file is needed. We are working on including both Wi-Fi and Bluetooth example for 1MW. Hopefully, you will be able to see 1MW in future SDK releases.

                     

                    I hope that answers your question.

                     

                    Thanks,

                    Puja
