问题描述
- 用手机wifi连接开发板配置好密码的hostapd热点，要么连接不上提示密码错误；要么用一会VNC后，断开连接。
问题解决
-
在hostapd.conf的配置文件中，添加如下选项：
wpa_pairwise=TKIP CCMP
-
然后重新连接，发现问题解决，wifi不再断开连接，也不提示密码错误。
思考
-
根据hostapd官方文档的内容：
Set of accepted cipher suites (encryption algorithms) for pairwise keys
(unicast packets). This is a space separated list of algorithms:
CCMP = AES in Counter mode with CBC-MAC (CCMP-128)
TKIP = Temporal Key Integrity Protocol
CCMP-256 = AES in Counter mode with CBC-MAC with 256-bit key
GCMP = Galois/counter mode protocol (GCMP-128)
GCMP-256 = Galois/counter mode protocol with 256-bit key
Group cipher suite (encryption algorithm for broadcast and multicast frames)
is automatically selected based on this configuration. If only CCMP is
allowed as the pairwise cipher, group cipher will also be CCMP. Otherwise,
TKIP will be used as the group cipher. The optional group_cipher parameter can
be used to override this automatic selection.
(dot11RSNAConfigPairwiseCiphersTable)
Pairwise cipher for WPA (v1) (default: TKIP)
#wpa_pairwise=TKIP CCMP
Pairwise cipher for RSN/WPA2 (default: use wpa_pairwise value)
#rsn_pairwise=CCMP

大概是加密算法的配置，猜测是未配置传递密钥的加密算法，导致无法正确解密手机端传递的wifi密码。
