I am trying to send audio signal at 2 different channels(96 MHz and 99 MHz) using bladerf but not able to transmit at two different channels at same time.
Anyone knows how to use two TX channels? please in details

The sink block string argument "bladerf=0,nchan=2" needs to be added and the number of channels needs to be configured to 2. Please consider using gr-bladeRF since it natively supports MIMO in GNUradio.

Thanks for reply, and one more question i want to ask if i want to receive exact values of frequencies using bladeRF (e.g., 96.05 MHz, 99.7 MHz) so is it possible using python? cause i want to detect frequency at which audio signals are available.

It is possible to use python, please take a look at the Python txrx.py example script at
