Hi everyone, I'm writing a python script with which I would like to acquire the metadata of the data read by my bladeRF 2.0 xA4, however when in the sync_config I want to set a fmt=SC16_Q11_META I get an error telling me that module 'bladerf' has no attribute 'SC16_Q11_META', where I'm doing it wrong? here is an excerpt of the code:

-------------------------------------
import bladerf
import time

CHANNEL = 0
NUM_SAMPLES = 10000
TIMEOUT_MS = 10000

try:
dev = bladerf.BladeRF()
dev.set_frequency(bladerf.CHANNEL_RX(CHANNEL), 915e6)
dev.set_sample_rate(bladerf.CHANNEL_RX(CHANNEL), 10e6)
dev.set_bandwidth(bladerf.CHANNEL_RX(CHANNEL), 10e6)
dev.set_gain(bladerf.CHANNEL_RX(CHANNEL), 30)
dev.sync_config(
bladerf.CHANNEL_RX(CHANNEL),
fmt=bladerf.SC16_Q11_META,
num_buffers=16,
buffer_size=8192,
num_transfers=8,
stream_timeout=TIMEOUT_MS
)

dev.enable_module(bladerf.CHANNEL_RX(CHANNEL))
samples = dev.sync_rx(NUM_SAMPLES)
dev.disable_module(bladerf.CHANNEL_RX(CHANNEL))

except Exception as e:
print(e)
-------------------------------------

here is the version of my libs:
libbladeRF version: 2.5.0-git-f24abc35
Firmware version: 2.4.0-git-a3d5c55f
FPGA version: 0.15.3 (configured from SPI flash)

Thank you in advance.
Regards

Have a look at the `_bladerf.py` file. I think you meant to use `bladerf.Format.SC16_Q11_META`.

The error you're encountering is due to the SC16_Q11_META format not being available or recognized in the bladerf Python module that you're usingplanet clicker. The bladerf Python bindings might not include this specific format, or it might be named differently.
Replace the line in your script:
dev.sync_config(bladerf.CHANNEL_RX(CHANNEL), fmt=bladerf.SC16_Q11_META, num_buffers=16, buffer_size=8192, num_transfers=8, stream_timeout=TIMEOUT_MS)
