CC3235MODAS: Cannot connect nor scan depending on channel

Part Number: CC3235MODAS

Hi,

I had an occurrence where a cc3235modas could not connect to my AP. I started to make some test and saw some strange behavior.

With some channels it could be found with a scan and connect to, but not others.

Channel OK: 36, 40, 48

Channel not found: 149, 153

To make sure there was no filter, I set and check ChannelsMask, it shows correctly 0xffffffff which indicates no filter

        Option = SL_WLAN_GENERAL_PARAM_OPT_SCAN_PARAMS_5G;
        _u16 OptionLen = sizeof(SlWlanScanParam5GCommand_t);
        ret = sl_WlanGet(SL_WLAN_CFG_GENERAL_PARAM_ID, &Option, &OptionLen, (_u8 *)&ScanParamConfig5G);

While the cc is not able to connect, my computer could connect correctly and shows the correct channel.

I am using the latest sdk and service pack from a few days ago, and the access point is a ubiquity ap ac lite.

Any idea where the issue could be?

Best regards,

Cédric
