    Attached it to adafruits FTDI friend, and works at low speed right out of the box

    Delivery was very fast and the product looks good. I am yet to try it with an Arduino but will hopefully work as described

    I have used these in the past with great success in close range. I have recently deployed a set of these for a weather station. Transmit distance in my application is 200+ feet, through three walls of the house without issue. So far it has worked down to 30 degF. I followed the setup instructions found at Seed Studio on this device. When setting up the device, type in the command verbatim as found in the data sheet, including the + sign. Additionally, these devices will not tolerate being wired incorrectly.

    I waited for 28 days for these modules to arrive in South Africa. I managed to get some info on the modules on YouTube, and links to files (https://www.youtube.com/watch?v=DGRPqeacJns). I have tested a pair of these at the lowest power level and 9600baud, and was able to get range of about 30m (indoors). Will still test further when I get time. One thing you can look out for: If you are using PUTTY for your terminal session, and the device is in "setting parameters state", i.e. 'SET' pin in 'LOW'

    Nagyon bejött. Városi, rádiózajos környezetben több falon át küldött adatokat nagyon megbízhatóan. Távolság próbát még nem csináltam vele, de nem tartom kizártnak hogy hozza az 1km-t is... Marha egyszerű használni, tényleg csak RX, TX-re kell kötni, és onnantól mehet a kommunikáció, nem kell hozzá semmi. https://www.instagram.com/p/BN_WHV4gzRx/?taken-by=outstanda

    I already have bought ~20 modules of them because the are really good. At my actual order, i got modules with firmware HC-12_V2.4 From my old orders i have modules with firmware HC-12_V2.3 It seems there is no good connection between modules with different firmware. Is there any way to up/downgrade the firrmware?
