Hello,

I am currently working with a custom PCB with a STM32F415 micro and BCM43438 wifi chip (SPI communication).

I have successfully flashed the snip.scan app, however I'm getting empty results:

# Type  BSSID            RSSI  Rate Chan  Security        SSID

----------------------------------------------------------------------------------------------

Scan complete in 893 milliseconds

(malloced_scan_result.status is equal to WICED_SCAN_COMPLETED_SUCCESSFULLY)

I suspect the issue may be an invalid wifi_nvram_image.h: I'm currently using the one provided by platforms/BCM943364WCD1.

Is this compatible with the BCM43438? If not, where could I find the correct image? gangiielec

Any feedback is dearly appreciated!

Thank you,

David

PS: I'm running WICED-SDK-3.3.1.

Resolved! The issue was indeed with the WiFi NVRAM Image: setting "xtalfreq=37400" fixed it, as the BCM43438 clock speed is 37.4Mhz.
