  Hi,

  Does somebody succeed to use the SX127x lora module with espruino to connect with thethingsnetwork ?

  To register the device on TTN, we must use the device EUI which is a uniq address hardcoded in the module.
  With the RN2483 espruino module, we can use the "getStatus" method to retrieve this information. Unfortunatly, it seems that SX127x doesn't provide this information (https://www.espruino.com/modules/SX127x.­js).

  How to get the device EUI with espruino?

  If someone succeed to to connect to thethingsnetwork with this module, please share you code because the documentation of the module is not a big help :(

  Answer to my own question: the RST button works perfectly with Espruino if you don't forget to call the "save" function to save your code in the board. Always read the doc...

  Thanks @guycreate, I received my two TTGO boards and it was really easy to install Espruino on it.
  I started to play with it and it sounds really promising :)

  Do you know if it is possible to use the built in RST and PRG buttons with Espruino ?

  Here is the pin diagram of my board: https://ae01.alicdn.com/kf/HTB1V_aBbTnI8­KJjSszbq6z4KFXaH.jpg

  I don't know which pins correspond to these buttons :(

  Does someone already tried to install Espruino on the Heltec/TTGO/Lolin/WEMS (or any of its dozen names) esp32 lora board?

  This board features:

  • an esp32 controller
    
  • a sx127x lora module
    
  • an OLED screen (don't know which model)
    
  • a cp2102 micro USB interface
    
  • a battery connector and charging circuit

  The controller is an ESP32 so I guess that it's possible to flash it with Espruino but I'm not 100% sure...
