  When I tested it 2 years ago, it worked, but it was really big already, far more than it has to be for the work it actually does. I guess people do not really have microcontrollers in mind Now, express have been developed further over time. Modules have the tendency to bloat over time and that will have happened with express, too... I suggest writing your code without express. In any case, it will behave faster. Thomas

  I would suggest adding this as a native C/C++ module. The only thing we need to do for this, is actually export the ESP-IDF functions to do this. A simple update of low.js. I think it would be the RMT module which is needed. Here is the native C/C++ module documentation: https://neonious.com/lowjs/documentation/lowjs-native-api.html Do you think you can undertake this? If the result is really nice, we can then integrate the native module in the official distribution of low.js if you like. Thomas

  Hi! oh, now I understand. No, that it is currently not supported. If you need it, please tell. But on the current roadmap, it is not a priority. Thomas

  You need to set wifi.enabled = false, then Wifi is off. Bluetooth is always deactivated with low.js, we did not implement Bluetooth yet, we would need a sponsor for that.. Light sleep is also not possible yet..

  That's too bad, I was hoping to use it in some hobby projects but looks like I'll have to take a stab at using Espruino for it since they do seem to have support through the neopixel library. Anyways, thanks for you answer and if this functionality is ever implemented I'd definitely love to check it out.

  I am using udp at the moment in the first layer of my control and data aq system which I am porting from Nodes hosted on linux embedded or windowsPC. At the moment it seems. UDPserver.address() only provides the host IP adress on connected sockets. Until a connection is made it seems that the host adrress in the tcp/ip layers is not initialised. UDP.connect is also not supported at the moment (dont need it anyway) but a UDP connection will cause the local hostip to become correctly populated and server.address() will work ON my PC. Soon I will be implementing my tcp socket connections so I will come back to this problem then . As I assume tcpserver.connect is impemented and therefore this method will work. As I also have a dedicated (application) server in my system infrastructure it will be no problem in the future to obtain the IP address this way. However, for other applications using DHCP (most serious iot apps I think) it would be nice to know the IP at start up time, particularly if the module is roaming. Instead of implementing the interfaces part of the OS module I would suggest you just provide a private function call to pull this up from the underlying DHCP client. I'll be back.

  No, there is no code example. If you want to build one and are willing to share it, I would gladly add it to https://github.com/neonious/lowjs_esp32_examples/tree/master/drivers Thomas

  lowsync now shows the correct 507 no space error in this case. I tried out express myself. It runs out of memory, correct? Have this in the list for some time in the future. Till then, I would recommend not to use express. It is, after all, a large framework, and even when it works, it will be slowing down the microcontroller much.

  Finally back from vacation! As answered directly after you sent the question via email on the same day: socket.io works with low.js. I am sorry, neonious one does not support PoE! To give some more insight: A PoE Splitter will work. The neonious one has 100 Mbit, so it only needs 4 of 8 pins There is currently no plan of supporting PoE. Maybe you want to take a look at the ESP32 Ethernet Kit Board, it is fully supported by low.js!

  Right, it is connected to a breadboard, and twiddling the components a bit do help, so it is probably a poor connection. Thank you for your help.

  Theoretically, all npm modules can be installed. Over 350,000. Just too many packages to show. So, no.. But you can look for the package you want to have elsewhere, maybe at npmjs.com, and then when you know the package, install it through the IDE.

  I do not think this is a bug. The password belongs into lowsync.auth.config.json, not into lowsync.config.json . Reason for this is to have a seperate file which might not go into your repository but rather stay local. If you add the password in lowsync.auth.config.json like this: { "password":"12345678" } Does it work? Thank you, Thomas
