TS-7970 WIFI

From embeddedTS Manuals

The TS-7970 releases prior to F included the LSR TIWI-BLE using the TI wl1271 chipset. When this went end of life the rev E boards were changed to support the Silex SX-SDMAC2832S+ module based on the QCA9377 chipset.

1 Silex WIFI (Rev F or later)

This board uses the Silex SX-SDMAC2832S+ based on the Qualcomm QCA9377 chipset.

Key Features:

  • FCC/IC/CE/MIC Modular Certification
  • Dual band, 2.4GHz and 5GHz
  • Station, AP, and Monitor mode
  • 802.11 a/b/g/n/ac
  • Bluetooth 4.2 (BD/EDR/LE)
  • -40 to 85C operation

Linux uses the "wireless-tools", "wpa-supplicant", and "hostapd" packages to support most of the functionality in this module. Refer to the distribution support for #Yocto, #Debian, or #Android for more information.

The module can be put in monitor mode where it can capture packets. The driver must be loaded with connection mode 4 to support this:

modprobe -r wlan
modprobe wlan con_mode=4
ifconfig wlan0 up
iwpriv wlan0 setMonChan 36 2
tcpdump -i wlan0 -w test.pcap

This will generate a test.pcap that includes raw wireless frames.

2 TI WIFI (Rev E or earlier)

This board includes a TiWi-BLE SDIO module that uses the Texas Instruments WL1271L Transceiver. Linux provides support for this using the wl12xx driver. See the LSR site for detailed product information.
