 Okay, so you're live. Okay. Yeah, I was kidding. All right, this is another lightning talk of five minutes. Is there another one that wants to queue up after this talk or not? Yeah, just a few minutes. Then you can, okay. Okay, let's go. Okay, hello, hi. Wanted to talk about a small project that was very useful for me. I had the problem with to get out of band management, out of a router, an open debate router that's typically have a serial console over 3.3 volts. And I thought about using Wi-Fi to extend that console and accessing it remotely. So I used the ESP8266 board where I used a firmware called G-Link made by someone, a community and a company in Holland. So see, this is an open debate router with three wires, one for ground, one for TX, one for RX, and the ESP8266 board. So the firmware is from G-Labs called ESP-Link. And it has a nice web interface where you can specify the boat rate that you want. And there's also a nice GUI for the Wi-Fi. So you can scan the Wi-Fi, choose your access point, put your key, I want to connect to that one. Everything through the click on home. So one interesting thing I did was to tell nets. So you can tell it to the IP of the ESP on port 23 and then you get the serial console out of that. There was some option where I had to pass this mode character so otherwise the back was not working. What I also did was I wanted to have the serial console but on transfer it to my laptop so that my laptop would see a slash def TTY USB zero. And then I used the SOCAT option. So SOCAT is TDIO TCP connect to the IP address of the ESP. And then the second option is SOCAT PTY and then link to slash def Vmodem zero. So Vmodem zero is the new dev entry I want to behave as I would have a standard cell port on my laptop, put some weight slave and then specify the IP address of the ESP 8266. And then I could do a screen over this serial interface and have the console as I would have had with a normal USB to serial adapter. One thing I was so experimented with was to send files with a Python program called serpai.serio.py where you do serio.py, the file, the destination and then the dev entry and it took in timings I did for 100 K file, it took eight minutes. So this is 1.2 kilobyte per second. A one megabyte file would have taken 85 minutes or one hour 25 to complete. But there are ways to specify high board rates but that needs to be, the target needs to be configured. One thing I wanted to do was a commercial device take an ESP in the right form with some kind of headers that you can choose with the jumpers all the combinations possible with the pins. And then normally on let's say open WT routers you have four pins, the VCC in 3.3, the ground, the TXRX and have directly an ESP on there connected to that and then furthermore have some kind of server device some cloud stuff where I could send this and optionally also even encrypt it so that on the other side you could connect to the server and then have a console back to your device. So that's pretty it. All right, thanks. Again, if there are questions please see Benjamin outside. So we have a few minutes until the next talk. So who is it? Alvaro should be here. So he doesn't know, but actually it's just not findable. The room? Yes. Yeah, yeah, I know, yeah. Yeah, and also it changes every year so. Yes, exactly. So I thought you were going to have a building Perfect. Right in time, that's great. Otherwise you're losing precious minutes. So this right there is the end.
