Another good day!
I can not wait for the new 2.2nH and 2.7nH from chip reseller. So I just get two 2.7nH from my old board then solid it onto VoCore v0.3, now it works. Fantastic!
Here are some screen captures from my board:
ZakeNetwork is a HiFi router, the distance from VoCore is about 8m(-70dBm), another is about 1m(-40dBm).
Using command iw dev wlan0 scan | grep -E ‘SSID|signal’
Pictures from the new wifi valid VoCore v0.3.
