Hi. I use BCM43143 on SDIO on Linux 4.8.17 with TI Beaglebone like hardware.
Have 2 issue:
1. BCM43143 does not see all WiFi networks. For example it does not see (not scanned) soft AP from my Android phone. I try different countries (crda), and its looks like not country issue.
2. Speed is to slow. I test with iperf3 and wget and WiFi speed is less then 1 MB/sec with good signal:
# iwconfig wlan0
wlan0 IEEE 802.11 ESSID:"Promwad Test"
Mode:Managed Frequency:2.412 GHz Access Point: 04:18:D6:35:4E:C8
Bit Rate=72.2 Mb/s Tx-Power=31 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:on
Link Quality=64/70 Signal level=-46 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0

Note: driver load brcmfmac43143-sdio.txt. Could you please provide sample of this driver, may be my brcmfmac43143-sdio.txt is bad.

I am not familiar with a BCM43143. Which partner module are you using in production?
