The default firmware of the LR2 SE (ELRS 2.4G) and LR3 (ELRS 2.4G) manufactured by our company is
ELRS V2, which can be updated to ELRS V3 protocol firmware now.
If you want to upgrade your old radio controllers, follow the steps below:
1. Download the corresponding firmware of the radio controller;
2. Download the BETAFPV Configurator V2.0-RC1 version , then install it;
3. Note: Only BETAFPV Configurator V2.0-RC1 version can be chosen if you want to configure the
radio controller, and you must select the serial port like the pictures below when
connecting to the configuration page.
Note from BETAFPV:
