QUESTION

How can I change the RX sensitivity or TX gain of Dolphin Based modules with DolphinAPI?

ANSWER

TX Gain

To change TX gain (performance) you can use different Radio Settings. The radio settings are optimized for several TX powers, please see this article for details.

RX Sensitivity

The RX sensitivity can not be changed by software. But there is a feature that still allows us to filter based on telegram RSSI. The Dolphin Module marks every received telegram with the dBm value with which was the telegram received. The DolphinAPI can then filter telegrams with lower / higher value from one you can specify. This features is called filters. Please see this article for details.
