Original question:

CCS/LAUNCHXL-CC1352P: Project Zero does not launch with Extended Advertising Type

CCS/LAUNCHXL-CC1352P: Project Zero Trouble with Extended Bluetooth Advertising.

Mark Shughart1

Part Number: LAUNCHXL-CC1352P

Tool/software: Code Composer Studio

I looked at this post (https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/t/906769?tisearch=e2e-sitesearch&keymatch=project%252520zero%252520extended#pi320995filter=all&pi320995scroll=false) and was still unable to see Project Zero advertising via iPhone, Android, or BTool. I had tried modifying some parameters from the Bluetooth training modules, but could not get a response to scan. Eventually, I tried a fresh project with just the advertising changed from "Legacy" to "Extended" (as Bonus Task 1 – Initiate Long Range Connection in the module) and with the status = .... commented out from the above post. 

My eventual goal is to test the range of long range bluetooth in application situations, so if there is a better solution than loading the 1352R launchpads/ sensortags, please let me know.

    Hi Mark,

    What version of the SimpleLink CC13x2/CC26x2 SDK are you using?

    What advertising parameters are you using? One ting to note when moving from legacy advertising to extended advertising is that you are no longer allowed to advertise scannable and connectable. You can be either scannable or connectable. Please see the Scanning and Advertising SLA lab:

     

    You can test the Bluetooth range with SmartRF Studio: Just use BLE settings.

    Marie,

    I'm using cc12x2_26x2 4.20.01.04 as the basis for this project. I had gotten the simple_peripheral device example working for that module before the followup module uses Project Zero again. The Project Zero documentation indicated no changes, other than changing the drop down to "Extended" advertising was needed. When combined with the linked forum post, I would have expected to be able to see the project either through BTtool with another sensor or through a phone.

    I will look into SmartRF for distance testing. Thank you.

    Hi Mark,

    As I said, in addition to adding the "Extended" property you need to remove either "scannable" or "connectable". (Or both.)

    Did you configure Btool to scan for extended advertisements?

    I change the "Legacy" Advertisement Type to "Extended" and the Event Properties change. That only allows scannable or connectable. Like the module you sent, I opened ti_ble_config.c and searched for ADV_SCAN_IND when I used connectable option. There was no result found, so it should be good. I got another Launchpad so I can use the SmartRF Studio directly.
