so im making a remote controlled tank/rover/car thing, its built on a repurposed 3D printer board with an atmega1284p. i have an esp32-cam that im planning to use as receiver/image sender, and im wondering if i understand the bridge widget correctly: i put the library in both sketches, give them each their own auth tokens, and can control either from one app? would i not need a wire between them somewhere?
Bridge is used when you have two devices that connect independently to the Blynk server, and you want to pass data between them.
That’s not the case in your scenario, as only one device will have connectivity to the Blynk server.
It’s difficult to say any more than that, as so much depends on what you’ll be doing with this custom hardware.
ok so not quite. is there any way to extend a blynk connection to a board that lacks networking? or is it gonna be easier to just read gpio pin states and have a table for motion?
It sounds like that’s the best option.
