Ping2 sonar issue with firmware update as well as showing error and prearm rangefinder1 no data

[Prashanth_u (Peashanth)]

Hi, I have used USB to TTL converter, wanted to connect to ping viewer software. As It is detecting automatically but when i tried to update firmware each time I connect the firmware version shows different, below are the images. when connected to 9600 baudrate the firmware version is different compared to 115000 baudrate

I have been trying to clear this from past 2 days, but still the error. And failing to initialise. Please suggest to solve these error.

Hi @Prashanth_u,

Support for flashing Ping2 firmware versions was only recently added to Ping Viewer. Please make sure you’re on the latest Ping Viewer version before attempting to update firmware on your Ping2 device.

Hi @eliot

The sensor is connecting to the software but I wasn’t able to update to the latest firmware as it is showing some pop-up error.
