  The BG96 issue is solved by switching the RX and TX pins within Serial setup:

  Serial1.setup(115200,{tx:PINS.LTE_RXD, rx:PINS.LTE_TXD, cts:PINS.LTE_RTS});
  

  Now the BG96 get GPS positions and the http get request works on Rak5010!

  I solved by using the poke32 to set/clear the P1.07 pin like this:

  poke32(0x50000300 + 0x518, 1 << 7);
  // set
  poke32(0x50000300 + 0x508, 1 << 7);
  // clear
  poke32(0x50000300 + 0x50C, 1 << 7);
  

  But the gps response was always:

  {"error": "Timeout"}
  

  The http get request always returns:

  {"code": -15, "message": "no response"}

  Hi Gordon,
  I need to activate the GPS power supply on the Rak5010.
  The rakwireless doc says to set the pin P1.07 to activate the power supply.
  
  But the P1.07 pin is not included into the RAK8212 espruino version.
  How can I add the missing pin?
  Thanks in advance ;-)

  Yes, I just flashed the .hex file and it worked except for the BG96 module.

  I'm using the standard build espruino_2v04_RAK8212.hex then I changed the pins values into the RAK8212.js and the lis3dh reference

  Do you mean the RAK8212.js file or the entire project?

  I noticed that the LED1 has the same old pin value but now I have to reset() it to switch on and set() to switch off.
  Maybe the same thing happens with the BG96...

  I'm trying this values:

  PWR_GPRS_ON : D31,
      LTE_RXD : D6, 
      LTE_CTS : D11, 
      LTE_TXD : D8, 
      LTE_RTS : D7, 
      GPRS_RESET : D29, 
      GPRS_PWRKEY : D28,
  

  instead of

  PWR_GPRS_ON : D6, 
      LTE_RXD : D7,
      LTE_CTS : D8,
      LTE_TXD : D9,
      LTE_RTS : D10,
      GPRS_RESET : D14,
      GPRS_PWRKEY : D15,
  

  But I'm not sure they are correct

  Hello Gordon,
  I developed a Rak8212 firmare using espruino.
  My firmware use the following sensors:

  • accelerometer lis3dh
    
  • the bluetooth advertising and gatt protocol
    
  • the bg96 module for gps and internet connection
    
    

  Now I'm trying to adapt that firmware to run it on the Rak5010 by using the Rak8212 firmware but changing only the pins values because the two schematic seem to be similar .
  For the lis3dh javascript module it was enough to change the interrupt and pins parameters, like this:

  i2c['setup']({"sda": D14, "scl": D13});
  lis3dh = accel['connectI2C'](i2c, {"int": D16});
  

  in place of

  i2c['setup']({"sda": D19, "scl": D18});
  lis3dh = accel['connectI2C'](i2c, {"int": D25});
  

  The bluetooth functions are working perfectly despite the nordic chip differences.
  But now I'm stuck with the bg96 module.
  Could you tell me if this is the right way to proceed or if there is other code to change into the espruino sources before I can use it?
  Thank you!

• Rak8212 and espruino: what is the lowest power consumption and how I could reach it?
