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
The bitmap is always the same. 0x1 for chain 0 0x3 for chain 0 and 1 0x7 for chain 0, 1 and 2 0xf for chain 0, 1, 2 and 3 Are you sure that your qca9880 card has 3 chains? Because the "Available Antennas: TX 0x3 RX 0x3" says there are only 2 chains available. It could be that the card physically has 3 chains, but the 3rd is disabled in eeprom. BR Matthias
