CC2541: OAD Manager sees my device but gets no further

Jim Seymour

Part Number: CC2541
Other Parts Discussed in Thread: CC2540

My code was originally built around the SimpleBLEBroadcaster sample - but I needed to add OAD support, so I switched to the SimpleBLEPeripheral sample.

After a few false starts, I now have code that compiles and links and even broadcasts like it did before.

However, the OAD feature does not seem to work.

First basic question: My code controls advertisements carefully and they are sent out with the "Non-Connectable" flag set.  Is that allowed in an OAD environment?

Assuming that's allowed, here's the rest of the story...

I successfully built the BIM+ImageA and programmed that into my hardware directly.  Then, I created an ImageB .bin with a new (larger) version number and loaded that into the OAD Manager running on a SmartRF05 board.  The LCD shows "OAD Manager" and I can use the joystick to select my device.  However, that's as far as it goes.  When I press the joystick down, the LCD does not change.

Any thoughts?

Thanks.

    Hi Jim,

    If you are using the SimpleBLEBroadcaster project with non-connectable advertisements, how are you connecting to the OAD Manager to perform the download? Are you switching to a connectable image? The proprietary TI OAD Target Profile only supports OAD during a connection.

    Please review the TI BLE Developer’s Guide for Over Air Download for CC254x for more guidance.

    Thanks for the response. Some of these details may be obvious to you, but they are not to me.
    Plus, I had a misunderstanding of a post made by one of your fellow Gurus that led me to believe the connectable status was not relevant to OAD.
    I'll start tinkering and see where it gets me.

    Well, no joy so far...

    I changed my advertising so that it uses GAP_ADTYPE_ADV_IND. I also made sure the contents of the advertising field use the GAP_ADTYPE_FLAGS_GENERAL flag bits. I even changed my service UUID from DEVINFO_ to SIMPLEPROFILE_ to match the SimpleBLEPeripheral example more closely.

    The end result is the same. The OAD Manager behaves itself through step 8 of section 11 in the OAD manual. On step 9, I push the joystick UP and it reports "Discovering...". Then, after ~5 seconds, it says "Devices Found 1" and I can select my device by pressing LEFT. But when I press DOWN, it says "SBL Mode..." and stays that way.

    Questions:
    1) Should the OAD Manager show something on the display immediately when it connects to my device?
    2) How long does a normal download take?

    Also, I just noticed that my firmware looks to be quite large (116,502 bytes of CODE space). Could that be a problem? I'm using a 256KB CC2541.

    Hi Jim,

    Are you able to complete the Out of Box demo with Simple Peripheral successfully?

    Thanks. Where can I find the "Out of Box demo"?

    OK. I think I know what you're talking about now. I pulled out the Quick Start Guide that came with my CC2540 Dev Kit and found that I can't get it to work as expected.

    One board was untouched and when I booted it up, it said "BLE Central". The other board was the one I was using for my tests - so I needed to reprogram it. I built the SimpleBLEPeripheral sample and loaded the CC2541 configuration into it - expecting to see "BLE Peripheral" on the display. But it remains blank.

    I notice that the RF daughter boards have CC2540 chips on them. Do I need to change the settings in the IAR project files? (They seem to be configured for the CC2541).

    OK. Nevermind. I'm an idiot.

    I'm so used to opening the CC2541 projects - since that's what my hardware uses - that I was opening the wrong SimpleBLE* projects. I've demonstrated to myself that the hardware works OK by going through the Quick Start Guide from the dev kit. In the process, I learned that the joystick is also a push button. I'd missed that detail before - so let me go back to the OAD manager and see if I can get it to behave...

    Stay tuned!

    Success! I have now downloaded code to my hardware using OAD. Thanks for the help - even if it was just forcing me to RTFM! :-)

    Hi Jim,

    I'm glad you were able to get your OAD to work! It's always good to go back to the basics to test your setup before tackling a more advanced issue. Please let us know if you run into any more issues.
