[Tinyos-help] AGC on CC2420

[Lei Tang]

Hello, guys,

I'm working on MICAz which uses CC2420, and have a question on Automatic
Gain Control (AGC) of it. Can we get the gain applied for every received
packet?

I set AGCCTRL on the receiver as default (0x07F0), and the transmitter sent
packets with variable power. But whatever the RSSI was, LNAMIX_GAINMODE was
always 3 (high gain), and the VGA_GAIN was almost always between 0x7B to
0x7E. We did not see any meaningful information on it.

Does anyone know something about AGC of CC2420? Please help. Thank you.

Best Regards,
Lei Tang
