I am currently fabing up a Cattle Weighing Platform for use in our cattle crush, using the OpenScale as the brains. It is hooked up to 4 x 500kg load cells and uses a ‘combinator’ of sorts to connect all four together, feeding 5 wires back to the OpenScale. Works very nicely when connected via serial to the laptop. However, reality check - cables coming out of cattle crushes, with agitated cows inevitably get crushed, kicked or just covered in cow dung (all outcomes are not good). Anyway, using the strengths of the OpenScale, we can go wireless (putting everything under the platform out of harms way) but I am having comms issues with the iphone and can use some advice. I tried multiple apps on the iphone, and found the app ‘ESP32 BLE Terminal’ was able to connect, and report the openscale data, but could not appear to write to the Openscale to open the menu, set tare etc. This is important as I need to reset the tare when we move the scale between farms. Any advice appreciated. Cheers,
The product page has this blurb:
“Bluetooth & Wired Config: Connect via Bluetooth/BLE or a wired USB-C/serial connection to access the terminal menu at 115,200bps. (Note: Terminal configuration via Bluetooth is not supported on Apple devices.)” :-/
WiFi Integration: Connect the board to your local 2.4GHz WiFi network to view your live data and perform Over-The-Air (OTA) firmware updates.
Do you have an Android device you can test instead? Most cheaper tablets should work fine. Based on the description, trying WiFi on the Apple device might work as well (you’ll have to set it up via bluetooth or wired connecton initially)
