Hi,
I am porting scan snip of Wiced SDK 6.4 to IAR.
It seems to work fine but :
1/ It display only channel 1 networks.
2/ The scan never end. (I never received WICED_SCAN_COMPLETED_SUCCESSFULLY or WICED_SCAN_ABORTED)
3/ If I manually set a channel with "wwd_wifi_set_channel( WWD_STA_INTERFACE, 6 )" I only see network present on channel 6.
When I read code, it seems that the wifi module should automatically scan all channels and return WICED_SCAN_COMPLETED_SUCCESSFULLY without intervention of the SDK during the scan. Does it correct ?
Any idea of which parameters/setting can set the WIFI module to scan only 1 channel and never end ? (I probably missed a #define while transferring code to IAR)

OK, it works !!!!
The issue was :
- LPO pin should be wired to a 32Khz source (PA8)
- DON'T comment #define WICED_USE_WIFI_32K_CLOCK_MCO (Event if the comment say you can...)
