1、AP6212 和 AP6210 软硬件设计部份差异说明：(1) AP6212 采用的是 26M 无源晶体从 PIN10,11 输入，而 AP6210 是 26M 无源晶体经过一个反相器之后 从 PIN30 脚输入，如下图，如果用 AP6212 A 框要去掉，即不需要再接反相器,并接上接上 R47=R48=0R,；
2、(2) AP6212 硬件上 PIN29 脚悬空，而 AP6210 是接上拉； (ps.如果 26M 时钟没有做兼容从 PIN10,11 进去，接 AP6212 的时候，可以尝试把时钟从 PIN10 脚输 入,PIN29 同时上拉)
3、(3) AP6212 要更新 bcmhd 新驱动 1.201.34.x/1.201.59.x 或者更新的版本，目前已经更新给主控原厂，请 从主控原厂获取最新驱动版本，另外固件包 firmware &Nvram 也需要从主控原厂更新，验证的办法 是：打开 WIFI，抓出 Kernel 的 log，检查打印信息，如果打印如下信息，说明 AP6212 已经正常工作：<4>[ 155.620641] Dongle Host Driver, version 1.201.59.2 (r491657)<4>[ 156.115862] Final fw_path=/system/etc/firmware/fw_bcm43438a0.bin<4>[ 156.115908] Final nv_path=/system/etc/firmware/nvram_ap6212.txt <4>[ 156.115956] Final conf_path=/system/etc/firmware/config.txt<4>[ 156.217659] NVRAM version: AP6212_NVRAM_V1.0_20140603<4>[ 156.218698] dhdsdio_write_vars: Download, Upload and compare of NVRAM succ
4、以下是 AP6212 吞吐量测试，分别为只开 WIFI，和同时打开 WIFI 跟蓝牙的性能测试 只开 WIFI，吞吐量： 50Mbps 打开 BT，吞吐量: 30Mbps1.
