Hi all,I see some very odd behavior with a B210. I have this simple sine flowgraph attached. My RX and TX antennae are approximately 1m apart. I just send a sine and receive it with an acceptable power level.
Though, my application uses burst transmission. Here, things start to fail. For some reason, TX bursts have very low output power. I make sure, all bursts are scaled to match the output level in my `sine_test.grc` flowgraph.
With 2 N310s, I can observe very reliable communication. If I swap one of those for a B210, I'm barely able to receive a B210s own bursts. I set TX gain to 90 and I could observe an improvement. Though, this is still far from what I'd expect after my sine test.
Is there an issue with burst transmission and B210s? Do I need to take any special precautions?
