  @allObjects Sorry if I wasn't clear. Gordon implemented a simple callback fix two weeks ago (see https://github.com/espruino/EspruinoDocs­/commit/8ca56d2929298152f683e4309bf876e7­35034216#diff-71fd1b58c3b419a0205973a478­fd66da5ff6b2c138a5e4a35cfbbb2e129c06b0 ) after our initial discussion earlier in this thread, but I only noticed it after I created my own fix using Promises when I was looking to contribute it back to the code base. I was just wondering when his fix would be published to .../modules.

  @Gordon I just spent three hours rewriting the SX127x module to use Promises, got it working, and when I wanted to create a PR I discovered that you already fixed it by adding the callback code 😂️

  Callback code works fine 👍️

  How does it usually take before the changes on master are available for use?

  Hmm, that makes sense but it didn't resolve it either. I tried increasing the timeout from 10 to 100ms, and putting the onIRQ setInterval inside the timeout function, but no luck so far.

  Why does the following code work just fine on the Pixl.js when code is uploaded to RAM, but when I use "Save on Send (to Flash)", or save() it wrapped in an onInit() function, does it just print "Sending.." and then stop?

  SPI1.setup({ sck:D3, miso:D4, mosi:D5 });
  var sx = require("SX127x").connect({spi: SPI1, cs: D6, rst : D7 });
  
  var config = {
    forcePaBoost: true,
  };
  clearInterval();
  // Until DIO0 line irqs are implemented we need this:
  setInterval(function() { sx.onIRQ(); }, 100);
  
  sx.setTxConfig(config);
  
  console.log('Sending..');
  sx.send("Hello", function() {
    console.log("TX done");
  });
  

• Lora and Espruino

  I just got LoRa comms working between a Pixl.js (connected to a RFM95W module) and a TTGO ESP32 LoRA board using the SX127x module!

  Now I'm wondering how difficult it would be to add a LoRaWAN stack. It appears these are two actively developed stacks that could be ported:

  • https://github.com/mcci-catena/arduino-l­mic
    
  • https://github.com/LacunaSpace/basicmac
    
    

  I imagine that should be easier than writing a JS LoRaWAN stack from scratch?

  Then there are the new STM32WL chips that have an integrated SX126x radio. So now I'm also wondering how difficult it would be to port Espruino to the NUCLEO-WL55JC dev board and get LoRa working on there?

  Thanks so much for the code example! I spent most of Friday evening trying to get this to work, but still no dice. I hooked it up to the logic analyser again, and noticed that the timings on the Pico are not as accurate as what I originally though, but it still works, even though similar timings on the Pixl.js are not working.

  Would it at all be possible for you to try and reproduce the issue with Pixl.js and the remote control sockets, just so that we know I didn't make a mistake somewhere else?

  Hi @Gordon! Did you manage to look into this issue more at all? I know you were working on https://github.com/espruino/Espruino/iss­ues/1749, but that didn't seem to resolve it.

  If this is not fixable in the near future, how would I go about using SPI to do it? Would I just set up hardware SPI and write it out on the MOSI pin?

  Gave it a try, but the Pixl.js pulse train is still 29.7ms.
