LP-CC1352P7: How to enable TCP communication in ti-wisunfantund

Part Number: LP-CC1352P7

Tool/software:

Hello TI team,

I referred to the following post:
CC1312R7 Wi-SUN Stack - Is TCP traffic supported?

In my setup:

  • For the border router (ns_br_src), the NO_TCP macro is commented out in cfg_ti_ws_border_router.h.

//#define NO_TCP

  • For the router node (ns_node_src), both NO_TCP and NO_IP_FRAGMENT_TX are commented out in cfg_ti_ws_router.h.

//Additional Optimizations
//#define NO_TCP
#define NO_IPV6_PMTUD
//#define NO_IP_FRAGMENT_TX
#define NO_MLE

However, TCP packets still cannot be transmitted or received between nodes unless ti-wisunfantund is modified.

Could you please advise how to modify ti-wisunfantund to enable TCP communication over Wi-SUN?

Thank you in advance.

Best regards,
Hyunkoo Ryu
