    I like wemos d1 with ESP8266 so I thought that getting wemos built esp32 board would be good as it also has 4MB flash available. See https://www.aliexpress.com/wholesale?cat­Id=0&initiative_id=AS_20170420235556&Sea­rchText=LoLin32 Would this be a good board to get to start playing with the ESP32 Espruino?

    Hi!

    Just reading about the new ESP3212 (on sale at seedstudio). Wouldn't that one be a good candidate to run Espruino on?

    I think about Bluetooth PAN as a way to get espruino on the net. Having a server with a bluetooth dongle for supporting PAN would suffice.

    I am also not sure how does it actually work under the hood (yet).

    Hi!

    Has anyone thought about hooking espruino to the net using bluetooth tethering? Anyone having an idea on what would it take to make this happen?

    Well, not for Europe I am affraid ;(

    United States Postal Service Priority Mail Express International $46.00 - $58.00

    The W5100's would ship free anywhere on the globe. $10 vs $20 is still very significant when you want to build a network of devices :)

    Hi!

    I would also like to get something more common. Getting the Wiz550io is like $17 for the module itself and $40 for shipping. eBay is full of W5100 Arduino shields under $10 (free international shipping).

    Do you think the w5100 would work with some of the tweaking mentioned above? Or is there any fundamental problem? From what I can see is that the w5500 has double the internal buffer and number of channels. Something I could live with wrt features.

    Any hints welcome!

    Hi!

    I selected our house Garage & Entrance Gate mobile phone remote as my first real embedded device project ever with espruino. I have got background in low-level driver development as well as modern single page web apps recently it would hopefully turn into something at least functional.

    I can already see it is not going to be a single technology thing. One would be the Garage door remote in use 'Hormann-HSM4-868-MHz-4-channel' and the other Nice Robus 433MHz-based remote. I read that both implement 'rolling code' security and I am not sure I should dig too deep into emulating any of those really (if you have any experience with those I would not be hesitant to hack around this a bit though). Rather I think I would just buy spare remotes which I would hook directly to espruino board and just trigger the buttons with the digital pins.

    I have already tested the HC-05 module soldered to the main board and I was able to get an Android mobile Bluetooth terminal remote controlled espruino LEDs blinking in under an hour. I find the time to get something working amazingly short with the espruinos' interpreter approach.

    Eventually I would like to get an ethernet/wifi module and be able to control stuff using a web page loaded directly from the espruino board to the client's browser (no matter whether it is a mobile phone or a desktop browser or anything else).

    Best Regards
