CC3200AUDBOOST: Wi-Fi Audio App Wiki Page Clarification

Part Number: CC3200AUDBOOST
Other Parts Discussed in Thread: UNIFLASH, CC3200

Hello all,

processors.wiki.ti.com/.../CC3200_Wi-Fi_Audio_Application

The above Wiki page has two flashing stages (I'm going with the functional (flashed) mode using UniFlash 3.4 in both cases):

Stage No. 1 - Setup CC3200 Launchpad:
===============================
2. Functional Mode:

Flash the binary file available in <cc3200-sdk>\example\wifi_audio_app\ewarm\UniCast\Exe folder using UniFlash. Refer to Detailed instructions at Uniflash User Guide. (I first do a format, then flash the ServicePack binary, then program the CC3200 board)
Repeat above step for second Launch Pad (checked)
Ensure SOP-2 Jumper is removed after flashing (checked)
Stage No. 2 - Running Bi-Directional Audio Demo:
======================================
2. Functional Mode:

Press Reset (SW1) Button on both the Launchpads (checked, tried both AP and non-AP modes with jumper and without jumper)

Questions:
========
I was unsuccessful in discovering any of the boards using the SimpleLink Wi-Fi Android App (Pro version or not) by flashing any of the "wifi_audio_app" or "wlan_station"; however, I was successful discovering them in AP mode (extra jumper in place) by flashing the out_of_the_box image. From there (using the out_of_the_box, not the wifi_audio_app and not the wlan_station), I can go to the "Devices" page of the Android App, click on any of the devices, and change their settings by adding my home router information as indicated in the Android app. However, I can never get audio across the two boards nor even get the simple local IN/OUT audio loop working, whether I press any of the SW2/SW3 buttons on any of the boards or not.

1. Does the Audio BP also need to get flashed using the microUSB?
2. I am running out of ideas, please kindly help as I have been spinning my wheels for over two weeks without success.

Thank you all,
PeymanM

    Hi Peyman,

    1. No the Audio BP does not need to get flashed with any firmware.

    2. Please replace the call to SmartConfigConnect() in the ConnectToNetwork() function of "network.c" with a call to sl_WlanConnect() to make sure the application works independent of provisioning.

    Once the devices successfully connect to the LAN, these steps should work to get the devices connected and communicating. If they are not, please describe at which step doesn't match your observations.

    Thanks,

    Ben M
