Other Parts Discussed in Thread: AM3358, WL1271
Hi,
We have used TiWi-BLE Module from LSR(450-0064) on our custom designed hardware based on AM3358 processor.
The module works fine both WiFi (Station mode and AP mode) and Bluetooth.
We want to perform FCC tests and for that we have used the calibrator utility as suggested in below link.
http://processors.wiki.ti.com/index.php/WL127x_TX_Testing
We are using arago yocto build environment and kernel version is 4.4.32.
For WiFi drivers we have selected wlcore, wlcore_sdio, wl12xx, cfg80211, mac80211 all as integrated.
Functionality using those configuration works fine.
But the issue comes when I try to use the plt mode of the TiWi-BLE module.
Here is the sequence and output of different commands
dmesg | grep wl
