CC3100MOD: AP Mode, Deauthentication during UDP transmission

Thanks.

Our latest development head does indeed run very low on memory and seemed to be the root cause for my initial random problems. Changed to older, stable branch and got the SDK 1.3 partially working.

These Access Point configuration messages consistently fail with -100: (ASYNC CMD TimeOut event)

    int16_t err = sl_NetCfgSet(SL_IPV4_AP_P2P_GO_STATIC_ENABLE, 1, sizeof(SlNetCfgIpV4Args_t),  (_u8 *)&ipV4);
    int16_t err = sl_NetAppSet(SL_NET_APP_DHCP_SERVER_ID, NETAPP_SET_DHCP_SRV_BASIC_OPT, sizeof(SlNetAppDhcpServerBasicOpt_t), (_u8*)&dhcpParams);
    int16_t err = sl_WlanSet(SL_WLAN_CFG_GENERAL_PARAM_ID, WLAN_GENERAL_PARAM_OPT_AP_TX_POWER, 1, (_u8 *)&power);
    int16_t err = sl_WlanSet(SL_WLAN_CFG_AP_ID, WLAN_AP_OPT_SECURITY_TYPE, 1, (_u8 *)&security);

These calls succeed:

    int16_t err = sl_DevGet(SL_DEVICE_GENERAL_CONFIGURATION, &configOpt, &configLen, (_u8 *)(&ver));
    int retVal = sl_NetCfgGet(SL_MAC_ADDRESS_GET, NULL, &mac_address_len, (_u8 *)mac_address);

I also got socket accept working for TCP Command channel and for UDP transmit port running. (Though, it only works with some added delay caused by UART traces at the end of _SlDrvMsgReadCmdCtx() -function in driver.c).

So, while still not perfect, our application now runs on latest SDK and Firmware: I have now seen the Wi-Fi disconnect twice with this setup.

The Specification mentions Radio Calibration, and that would be required after 20 degree celsius temperature change. What will happen if that temperature change occurs while in operation? (CC3100 in AP mode, streaming UDP data to a client)

Hi,

This has been observed on iPad gen 4 and 5, iPad Air 2 and iPad pro 9.7 devices. This occurs also on Samsung Tab S3 device that we have, but probably a bit harder to reproduce there. (Though, the majority of our devices are iPads, which probably makes this seem more frequent with them.)

The AP and STA are kept within 0 - 2 meter range from each other. The signal strength of the CC3100 AP is significantly higher than other access points in range.

It is a custom board with CC3100MOD and AH316M245001-T chip antenna.
