Hi Team,
I added the CYW43455 WIFI/BT chip support in the Jetson Platform using the following driver/firmware Cypress Linux WiFi Driver Release (FMAC) [2020-09-25]
Wi-Fi is working but it supports only 802.11 a/b/g modes. And I am not able to use 5Ghz in AP mode.
1) How to add support for 802.11 n/ac modes?
2) Does 802.11 n/ac support added by firmware or any other layer of WIFI interface?
3) Is there any procedure/commands to verify the 802.11 ac mode?
Thanks,
Ajith.

1. Please refer to point 3 for details on setting the appropriate data rate for 802.11n/ac modes.
2. 802.11n/ac mode support is added by WLAN firmware and clm_blob file.
3. Please refer to sections 4.2.4.4 and 4.2.4.5 in AN225347 - Cypress Wi-Fi CLM Regulatory Manual for data rate testing using WL commands. Table 4.2.4.3 provides the specific WL command to set the data rate based on the 802.11 mode. The last table on page 13 provides the wl chanspec command based on the 802.11 mode. Accordingly, the WL commands in sections 4.2.4.4 and 4.2.4.5 can be modified.
For your reference, the following commands are relevant to 802.11ac:
wl chanspec 36/80
wl 5g_rate -v 0x1 -b 80

Hi GauravS_31
Thanks for the response,
1) Does the CYW43455 chip support ad-hoc mode in WIFI ?
2) Is there any procedure/command line tools available to setup ad-hoc network using WIFI interface ?
Thanks,
Ajith.
