Question

Is it possible to set the agc to a fix value ?

Hi,

I have a question about the BlueNRG2 device: is it possible to set the agc (automatic gain control) to a fix value ?

Maybe in the RADIO_CONFIG register ? But there is no info about the content of this register !

Thanks a lot !

Are you trying to adjust the transmission power?

Please try to call the ACI: ACI_HAL_SET_TX_POWER_LEVEL()

Not exactly. My transmission power is fix. But I would like to set the agc to a fix value.

I think agc allows to automatically control the gain of the signal at the reception. Then, the final RSSI (dBm) depends on a "raw" measured RSSI and on the agc. I would like to know if it is possible to fix this agc to a specific value.

On some other RF chips from ST, I saw that the agc can be enabled or disabled.

Note1: I am not using the ACI, I am implementing my code directly in the BlueNRG device.

Note2: I am not using BLE but only the Radio API.
