Hi
Thank you so much. You made my day!
The command works. Im looking forward to test it out :-)
I also have two of these card. they don’t have the same bitmap, but I assume
they work the same way?
qca9882 chipset with 2 chains available using ath10k driver:
Available Antennas: TX 0x3 RX 0x3
Configured Antennas: TX 0x3 RX 0x3
qca9880 chipset with 3 chains available using ath10k driver:
Available Antennas: TX 0x3 RX 0x3
Configured Antennas: TX 0x3 RX 0x3
Best Regards,
Håvard
