"Packet was scheduled but failed to Tx"?

[Federico Torres]

Hello everyone

We’re testing confirmed transmissions with a couple of nodes. Every once in a while, we have lost ack packets, but we can’t figure out why. In the packet forwarder logs, the only thing we notice is some CRC fails in Rx, and a “WARNING: [down] packet was scheduled but failed to TX” when there’s a downlink, but after that we see no Tx errors. Has anyone had the same problem?

This is the packet forwarder log:
