Hello, sorry in advance for the following very weird question.
Curious if anyone has played with the RF remote that are 315 MHz like these;
-- I'm looking to understand if they have a 'learning' code or they 'should' simply all work together without configuration. ex; getting many receivers (from different batches) all working with the same remote or not.
I bought a few units and the ones that were in a 'kit' where working great together, but the extra remote/board sold separately do not seams to be sending/receiving anything. (the small led on the remove is on when pressed)
The ones that sadly works is a very ugly brown remote with buttons that will jam and get stuck half of the time. so I'm looking for a more pretty remote.
The one on adafruit is pretty nice and looks to be available in Asia on sites like Aliexpress but before ordering a few hundreds I'd like to be sure to understand well how these works since my locals test are not looking good. *since the exact same remote from adafruit will not work on the many boards I have.
Receivers all have the same IC: PT2272-M4, but silk screen markings vary from RO2A to YK04.
I've made a very simple test bread board to validate remote/board functionality with LEDs.
and thus all remote seams to be labled with 315MHz not all receivers seams to be getting any signal.
so it's either I got a few receivers that are defective and all should be seamlessly working together or I've overlooked possible configuration, with some learning code to 'configure' the remote.
Thanks
