When I tried create softAP, nothing showed. I can scan the networks and see them, but when I tried connecting to one, it failed.
I got this error once when I was trying softAP example:
Code: Select all
W (460) phy_init: failed to load RF calibration data (0x1102), falling back to full calibration
This is whole log when I was trying the softAP example:
