Flashing Firmware

[EliotBR (Eliot)]

Hi @Alex3, welcome to the forum

@Alex3

I am trying to flash my ping sonar down from V3.28 to V3.27_9600b in order to use the Arduino code over 9600 baud rate (as I have other Serial components which run on 9600).

@EliotBR

we’ve just released an update to the ping-arduino library …, so that it’s now able to work properly with the 3.28_auto firmware instead of needing to downgrade it.

You should be able to install the latest version from the Arduino Library Manager

@Alex3

I’ve followed the instructions Firmware Update - Ping Viewer but when I click ‘Firmware Update’ the page freezes and doesn’t change/restart again.

This is a known issue that should be fixed in the latest version of Ping Viewer (which we’ve just released). You can download that from here or the installation docs, although you shouldn’t need to downgrade the firmware anymore (it’s better to update ping-arduino instead)

@Alex3

I have had this working with the Arduino example using 115200 baud rate.

As per our updated guide:

@Using the Ping Sonar with and Arduino - Firmware Version and Baud Rate

For flexibility, our ping-arduino example uses SoftwareSerial, which communicates with Ping at 9600 baud*.
…
If your microcontroller has an extra hardware serial port, you may use that instead at 115200 baud.
…

* SoftwareSerial may connect at 115200 baud, but behaviour and performance can be inconsistent, so it’s not recommended.
