WiFi Direct is possible between two CC3200 modules?

Other Parts Discussed in Thread: CC3200, CC3100

Hi All,

We have implemented the WiFi direct communicating between one CC3200 module and android device.

For implementing this I have used P2P application from CC3200 SDK with CC3200 launchpad only. The CC3101 SDK does not have P2P application.

1) I want to know whether it is possible to do WiFi direct communication between two CC3200 modules.

2) Also the CC3200 SDK is not loading the application after flashing .bin file using slprogrammer. But if we use the same slprogrammer for CC3101 SDK it is loading the application after flashing the .bin file.

Kindly assist me on solving the above issues.

Thanking you,

-Yasar Arafath.

    Hi,

    1. Yes, it is possible to do WiFi Direct communication between two CC3200 modules. Please see the below note from Network processor subsystem documentation:

    ***
    SL_P2P_NEG_INITIATOR_RAND_BACKOFF: When the remote peer is found after discovery, the device triggers a random timer (1 to 7 seconds). The device waits passively for the peer to negotiate during this period. If the timer expires without negotiation, the device immediately sends negotiation requests to the peer device. This is the system default as two CC3100 devices do not require any negotiation synchronization.

    This configuration should be used when working with two CC3100 devices. The user may not have a GUI to start the negotiation, thus this option is offered to prevent the simultaneous negotiation of both devices after discovery.
