Hi,

With CC2420, I'm trying to send a train of packets in a back-by-back way. "Back-by-back" means there is no CCA or backoff between two packets in the train. And there are about 100 - 200 packets in one train. However, I noticed that the packet train was separated into several pieces instead of sending in a complete train. It showed that the transmission was stuck somewhere in the train (the broken position is generally random). After around 2 seconds, the radio continued sending the rest train cars. For your reference, I've attached a plot with timestamp of each packet in the train.

Does anyone have any idea why this happens? Thank you very much.

Best,
Jiakang
