CC3135MOD: Disconnection reason and condition for CC3135MOD and WL1807MOD

Part Number: CC3135MOD
Other Parts Discussed in Thread: WL1807MOD,

Hello expert,

I have questions for the disconnection conditon for CC3135MOD STA mode and WL1807MOD AP mode.

1) As for CC3135MOD STA, I read wlan.h and found the disconnection reason codes , but how can I find the condition for each. For example, how much continuous beacon loss will be the reason of the disconnection?.

2) As for WL1807MOD AP mode, I found "">e2e.ti.com/.../the-issue-of-wl12xx-beacon-loss-detected" thread, then found 12 continuous beacon loss will be the reason for the disconnection, but this is for STA. Where can I find the condtion for AP mode? Also, where can I find the disconnection reason code like C3135MOD?

Regards, A.Fujinaka

  • Hi A.Fujinaka,

    The algorithm for beacon tracking (At least for SimpleLink) is more complicated than just counting the number of missing beacons. If the device is in LSI/PS then the device first disable the LSI, followed by extending the beacon reception (wake-up) window, until the device will be put in awake state and it will send some null data frames to check the status of the connection and only then it will trigger a disconnection.

    The thresholds (of moving between states) have been changed during the last few years and the info is only available internally.

    The reason codes that are used here were taken directly from the 802.11 specification.

    I'm not sure if wl18xx has similar definitions in its header files but the codes are public and can be found online.
