    BCM943341WCD1_EVB : BLE demo app

      The BCM943341WCD1_EVB claims that it supports both wifi and ble.

      From the wiced wifi sdk I am able to build and run a wifi based app, but am unable to figure out how to implement a ble peripheral.

      The wiced smart sdk seems to be geared towards BCM2073X.

          WICED SDK 3.3.1 SDK supports peripheral mode via a sample application called ble_proximity_reporter.

           

          Here's a couple of threads on the subject:


          Can SmartBridge support "peripheral" mode?

          BLE API's for peripheral mode

          Ch-_2119361 also has this working on the newer 4343W/43438 RedBear Duo board as well: Re: To IoT Lovers: RedBear Duo

           

          JaeyoungY_71 is also working on a Blog that covers this sample app which should be posted soon.

            Still getting used to the WICED SDK ..

             

            Two problems :

            a. unable to get serial output to show up

            b. need help setting up IDE with 3.3.1 SDK

             

            Unable to see serial output

            1. I downloaded and installed Wiced-SDK-3.1.2 for OS X.

            2. I was able to build and download the  snip.scan-BCM943362WCD4 download run (saw the blue JTAG leds flash appropriately, no errors).

            3. I setup CoolTerm but am unable to see any output on it (when evb board was connected I saw it show up as usb-serial-B and I setup baud and other comm parameters as specified in the quick start guide). However I am unable to see any output from the scan app on the CoolTerm window. Tried relaunching app from the debugger as well as pressing reset on the board. Interestingly if I hit kits on my mac keyboard I see the UART LED flash on the board (so the Tx from the mac is going through, just no Rx coming from the board). Plan was to try and step through the debug version of the app to determine what's happening, but if you know what might be happening will save me a lot of time.

             

            Adding BLE apps to the IDE

            Going back to your reply for setting up BLE.

            I downloaded the SDK-3.3.1 and copied the entire folder to /Applications/WICED (this is where I had installed 3.1.2)

             

            sajids-MacBook-Pro:WICED sajid$ pwd

            /Applications/WICED

            sajids-MacBook-Pro:WICED sajid$ ls -l

            total 8

            lrwxr-xr-x   1 sajid  admin   19 Jan  1 08:16 WICED IDE -> eclipse/Eclipse.app

            drwxrwxr-x  23 sajid  admin  782 Jan  1 08:20 WICED-SDK-3.1.2

            drwxr-xr-x@ 19 sajid  admin  646 Jan  1 09:44 WICED-SDK-3.3.1

            drwxrwxr-x  16 sajid  admin  544 Jan  1 09:49 eclipse

            sajids-MacBook-Pro:WICED sajid$


            How do I pull in all these projects from 3.3.1 into the IDE ?

             

            Just as an FYI ..

            My demo app needs to do the following :

            - connect to a phone over BLE

            - scan for wifi access points

            - send the access point info via a custom BLE service to the phone

            • 3. Re: BCM943341WCD1_EVB : BLE demo app

              Since I was unable to find SDK 3.3.1 pkg for Mac OSX I instaeed 3.3.1 on windows10.

              Now after I launch WICED IDE how do I add the ble_proximity_reporter project to the IDE so that I can build, download and run/debug on the BCM943341WCD1_EVB  board.

              • 4. Re: BCM943341WCD1_EVB : BLE demo app

                I dragged the ble_proximity_reporter folder to the  IDE's Project Explorer folder WICKED-SDK/apps/snip

                In the MakeTarget Tag I created a copy of "snip.scan-BCM943362WCD4 download run" and renamed it "snip.ble_proximity_reporter-BCM943362WCD4 download run".

                 

                Now when I click "snip.ble_proximity_reporter-BCM943362WCD4 download run" to build it I get the following error in the console :

                 

                tools/makefiles/wiced_config.mk:291: *** ble_proximity_reporter application does not support BCM943362WCD4 platform.  Stop.

                make: *** No rule to make target 'build/snip_ble_proximity_reporter-BCM943362WCD4/config.mk', needed by 'main_app'.  Stop.

                • 5. Re: BCM943341WCD1_EVB : BLE demo app

                  Added BCM943362WCD4 to VALID_PALTFORMS in ble_proximity_reporter.mk

                  Now get the following error :

                   

                  tools/makefiles/wiced_config.mk:304: recipe for target 'build/snip_ble_proximity_reporter-BCM943362WCD4' failed

                    First off, WICED SDK 3.3.1 under Windows (have not checked other versions) has an issue where not all of the included apps show up in the project explorer after the initial install.

                     

                    To fix this, within Eclipse go to the File->Refresh (F5) menu item.  Once clicked, you will see alot of new apps populate under the project explorer folder.

                     

                    One of these included projects is the previously mentioned proximity_reporter, specifically: /WICED-SDK/apps/snip/bluetooth/ble_proximity_reporter

                     

                    To run this program, you will need a BCM943341WCD1_EVB board such as the one you mentioned in your initial post (this board supports BLE/BT, the 43362 board does not - Wi-Fi only).

                     

                    First off, plug the BCM943341WCD1_EVB into your PC and double-click the "clean" make target; note that double clicking the make file in the make file window is the only way the SDK knows to load the program onto the board, the menu items in Eclipse do not work. This will confirm that the SDK can communicate with your eval board.

                     

                    Next, you will need to create a new make target file for the proximity reporter application, but the target will need to point to the 43341 platform, not the 43362 platform which is shown in the included examples.

                     

                    To do this, copy and paste one of the samples shown in the Make Target window.

                     

                    I took: snip.scan-BCM943362WCD4 copy-paste, then changed the Target Name to: snip.bluetooth.ble_proximity_reporter-BCM943341WCD1 download

                     

                    Notice the syntax used in the target name is essentially the mapping of the directory for the sample app, followed by the platform name. It the syntax is off even in the slightest, you will see errors thrown.

                     

                    Now double-click the new make target you just created.

                     

                    I cannot test this at home because I do not have a 43341 eval board, but this should work.

                     

                    If this does not work, you will most likely need to wait for the apps team to return to work on Monday.
