Timed out waiting for buf_ready

[improperaffo]

Hi all,

We are using a project (srsRAN_Project) which only supports UHD, so we are using SoapySDR as a wrapper to control our BladeRF xA9 via UHD. All the commands by UHD (e.g., uhd_find_devices, uhd_usrp_prob) work, but when we start transmitting via SRS, it seems like the buffers are not ready and we only get these errors:

[ERROR @ host/libraries/libbladeRF/src/streaming/sync.c:336] wait_for_buffer: Timed out waiting for buf_ready after 1 ms

We tried to downgrade the BladeRF's FPGA image and FX3 firmware to v0.11.0 (2019-07-31) and v2.3.2 ( 2018-12-16) respectively, but this doesn't solve the problem.

Does anyone have a solution for this problem? Thanks for your help!

Best,
Raphael

Greetings!

Have you got any success on solving this issue?

Yes, we set static constexpr double RECEIVE_TIMEOUT_S; and static constexpr double TRANSMIT_TIMEOUT_S to 0 (previously they had a value greater than zero.
