 Hello and welcome. Now to get to some practical examples. First of all, I will show you, I will show you the 80 slave assist in the... So if we send a simple 80, it should reply with okay. If we send 80 plus question mark, it will list all the commands. We need 80 conf first. So I have prepared a simple command that will transmit the or set the radio to 860 megahertz, spreading factor 12, etc., etc. Basically you can find all these parameters in the tconf right here. So it's defining coding rate, etc. And now if I do 80 plus ttone, it should transmit the unmodulated signal. So now if I add the cube monitor, what I would do if I had a clean dashboard, I can simply click import in here, select the file to import. I would go to my repository, find the WL package, projects, nuclear WL applications, lower one, lower one 80 slave. And here, as I mentioned, is the cube monitor folder. And here we can find the JSON that can be loaded into the cube monitor. So I will click cancel because I have everything imported. It will look just exactly like this, with the exception that the serial ports are not configured yet. I have them configured right now, but just for a showing purpose, I will change one of those and I will click deploy. And now I can hook up the dashboard, which is the graphical interface of the flows. Yeah, so basically I'm transmitting from this one the tone and the other one is receiving and measuring the RSSI. So as you can see, we have minus 16 dBm, which is very good signal. And I can also switch that. So 80 stop test. Now to configure it again, and this time I will measure the RSSI on this one. As you can see, I have minus 17, 117 dBm, so that means basically anything is received. And if I start here the transmission, I should get, yeah, I have a value of minus 14 dBm. So that is basically what the cube monitor is accessing. And now if I, this is the very basic test. So you have RSSI test and continuous wave test. So you can use one Nucleo and your PCB as the other board or just anything you need. If you need to measure it on then more precise equipment, you just generate the tone and that's it. So now I will switch my second port. So I will close this one. And now to configure this one, I need to click deploy again to have the changes. Click the dashboard. And now I should have both of the Nucleos connected together. And also show you like this. Now we can do a very simple test. I will reduce the power because they are right next to each other. So we have a bandwidth of 125 and a spreading factor of 12, conging rate 4 from 6. And as you can see, it's performing a very simple packet error rate test. So one board is transmitting, the other one is receiving and it's counting how many was received and what are the parameters of the signal connection. So we had a very strong signal, good signal to measure ratio and packet error rate is also zero. So good connection. I can also modify the parameters to have a higher bit rate. So it will perform faster now. You can also configure to use multiple frequencies. So it's transmitting only on 863 megahertz, but by step it goes higher. Now if you are also interested or if you are not interested in Lora, this flow also provides the very same tests for the FSK modulation. So you can test the very same things in here. The last test is a simple TXRX. So basically it's a fusion of the two I showed before. So one board is transmitting, the other one is receiving. So I will lower the TX power and start the boost. As you can see, one is transmitting, the other one is receiving. And now we can play a little bit more because if I cover the antenna, it should go a little to a little worse signal. Or if I add something more interesting, it should go even lower. And you can see how the radio is performing if you cover it, if you shield it, or whatever you need in your application. So what the note should we stand? Oh, it is disconnected just now. My cable is not very good. It goes lower. This is basically most of the application. There's also a little theoretical part that is the Lora airtime. So we can count or theoretically calculate how much time on air the transmission would be. So with the spreading factor bent wide, etc. As you can see, if I reduce the spreading factor, we will be faster, only 328 milliseconds, for example. So very simple application to quickly calculate the time on air. And the last part is the AT command. So basically, these applications also including a terminal. And you can also see what is sent to the device. So as I was configuring it manually, here is also the same command to configure the radio. There are some tone tests, and then some data comes in. This is all from my site. Thank you for your attention.
