I want to be able to uplaod\ chhange the code from another palce \ remote location

Hello,
wanted to know if there is a way to upload the code not using IDE ?
or somehow to intigrate it into my website using API ?

I'm using the MDBT42 only as a beacon - and I want to be able to change it's name when ever I want to

is this somthing reasonable to do ?
is there any way to do it?

*** I have created a virtual com to the device and using the webIDE I can uplaod to him the wanted code , so no netwrok issue
Thanks ,

wellll
it's seem that I had some problem in the computer that block me some websites......

I have try with another computer - and everything start to work

what a waste of a day!

so now its working and read the data every 10 seconds

Thank you for the help!

the computer is connected all the time to the internet

1. where it load the module , maybe something happand to the server?
   
2. if there was a problem , how could I upload the code before? what have change?
   
   

Thanks ,

I don't know what to say:

I have try to upload the code you posted(I'm write it so you will see no errors)

var mcp;
function onInit() {
  clearInterval();
  I2C1.setup({scl:D25,sda:D26, bitrate: 60000});
  mcp = require("MCP9808").connect(I2C1, 0b000);
  console.log("I2C Setup Finsih");
  ReadTemp();
}
function ReadTemp() {   
  setInterval (function() {
    digitalWrite(LED1,0);
    var temperature = mcp.getTemperature();
    var TimeStemp = new Date().toString();
    console.log(TimeStemp + "  :  " + "Temperature: " + temperature + " C");
    setTimeout(function(){
      digitalWrite(LED1,1);
    },5000);
  } , 10000);
}

onInit();

this is what I get :

Running onInit()...
Uncaught Error: Module MCP9808 not found
 at line 3 col 26
  mcp = require("MCP9808").connect(I2C1, 0b000);
                         ^
in function called from system

both on RAM\Flash uplaod

what is wrong now?

update*
I get the same error when I try to uplaod my own code that works before

2 questions:

1. to uplaod the new code on FLASH , right?
   
2. run "require("Storage").eraseAll()"
   anyway before uplaod the code?
   
   

*** update
when I run the erase I get this

require("Storage").eraseAll()
=undefined

Thanks ,

so what to do now?
I have change it to "Flash" but it say "Sent"
but still it stuck (can't do nothing on the console )
I have disconnect , and now I can't reconnect

I have reboot the device ,recoonet it
nothing is running now (no output on the console)
but I can "talk" with the device:

>new Date().toString()
="Thu Jan 1 1970 00:01:34 GMT+0000"

have try to run upload to FLASH
and this is what I get :

so what to do now?

** I have uplaod it now to RAM - and it's working (if it's help you to understand and help me)

Thanks ,

the address is OK
I have check in some i2c scanner

I think something is wrong with the flash memory
because I have upload the code using the esperino IDE in chrome this time , selected RAM
and it's working , it print me the data

this is the code:

I2C1.setup({scl:D25,sda:D26, bitrate: 60000});
var mcp = require("MCP9808").connect(I2C1, 0b000);
console.log("I2C Setup Finsih");


function ReadTemp() { 
  
setInterval (function()
             {
  digitalWrite(LED1,0);
  var temperature = mcp.getTemperature();
  var TimeStemp = new Date().toString();
  console.log(TimeStemp + "  :  " + "Temperature: " + temperature + " C");
  setTimeout(function(){
  digitalWrite(LED1,1);
  },5000);} , 10000);}

ReadTemp();

I have used upload to RAM
and it's working

now I have enter save() , in order to make it work after reboor\power off - everything
got stuck:
can't write nothing in the console
get no replay
the led is off

this is what I have in the console after "save()"

what to do now ? something went wrong ?

Thanks ,

after I wated all day connectiong the device using USB-serial
I have try to use the bluetooth option in the chrome ide - https://www.espruino.com/ide/#

I can see the device
I can connect to it
but I get this error

CONNECTED TO WEB BLUETOOTH, MDBT42Q 2E7E (NO RESPONSE FROM BOARD)

how could it be?
what can I do now?

I have try with another board
I get this error

CONNECTION FAILED.

I have only conneced 3.3V and gnd to the devices

what is wrong?

Thanks ,

another problem

I have try to upload this code

I2C1.setup({scl:D25,sda:D26, bitrate: 60000});
var mcp = require("MCP9808").connect(I2C1, 0b000); // 0b000 means A2 = A2 = A1 = GND 
var temperature = mcp.getTemperature();
console.log("Temperature: " + temperature + " C");

function ReadTemp() { 
setInterval (function()
             {
  var temperature = mcp.getTemperature();
  console.log("Temperature: " + temperature + " C");
  digitalWrite(LED1,1);
  }
  ,1000);}

digitalWrite(LED1,0);
ReadTemp();

I get no error while uploading ,
just see the bar running , then "SENT"
see the

then nothing - the device is not replay
nothing on the console , can't write nothing on it

I don't get any error - but it doesn't uplaod the code
after reboot from power - It run the old code (the one on the first post)
how could it be ?

Thanks ,

Hello ,
I have bought the MCP9808 and connect it

copy the code from here:

I2C1.setup({scl:B6,sda:B7, bitrate: 60000});
var mcp = require("MCP9808").connect(I2C1, 0b000); // 0b000 means A2 = A2 = A1 = GND 
var temperature = mcp.getTemperature();
console.log("Temperature: " + temperature + " C");

but I get this error:

in function called from system
Uncaught Error: Cannot read property 'getTemperature' of undefined
 at line 10 col 22
var temperature = mcp.getTemperature();
                     ^
in function called from system
Uncaught Error: Cannot read property 'getTemperature' of undefined
 at line 10 col 22
var temperature = mcp.getTemperature()

what is missing?
do I need to download something?
Thanks,

I know that the MAx30102 is also a temperture sensor
from the datasheet
https://datasheets.maximintegrated.com/e­n/ds/MAX30102.pdf

INTERNAL DIE TEMPERATURE SENSOR Temperature ADC Acquisition Time TT TA
= +25°C 29 ms Temperature Sensor Accuracy TA TA = +25°C ±1 °C Temperature Sensor Minimum Range TMIN -40 °C Temperature Sensor
Maximum Range TMAX 85 °C

I will figure the data out - but now I want to be sure the what you wrote can "read" the temp data

sometime you need to throw everythin and start from 0
took a new MAx30102 , new cables
now it's seem to be working
I get a grafh
So thank you for this!

I don't need the grafh - what do to in order to just see the values of the temp?
is it the rawdata?
Thanks again!

why?
what did I do wrong ?

I disconnected the max3012 and connect it to the arduino - it's working (so now hardware issue ) . did it just to be sure

great ,
wanted to be sure

and do you also know how can I use the code

Gordon

upload?

what do I need to in order to connect the device?

Thanks ,

meanwhile I will just try to see I can connect

// set up I2C
var i2c = new I2C();
i2c.setup({ scl : B6, sda: B7 });

what is B6\B7 - does it mean D6\D7 ?
and if I'm using serial also , can I connect it to D11 and D12?

Thanks ,

what are what are the chances that you have this ? :-)

if I wnat to use the code you wrote , what do I need to do?
I just want to be able to read the temp

Thank you so much!

and if not
what can I do?

I want to use the max30102 - but there is no "driver" for this
I have made a cool project with this device using Arduino now I want to use the Espruino
or maybe you can advise about a humen temperture sensor?

OK , great
1 more question before I start with the code
where do I downlaod the require library for the device I need?
where do I search if one exist ?

Thanks ,

can I connect to it an i2c device?

Thanks ,

I can see the phone with anoter device

hello ,
I have started a new project , and went back to basic because something isn't working for me
simple scan for devices and print them
this is the code:

NRF.setAdvertising({}, {name: "Test3"});

var s=setInterval(function(){
LED1.write(false);
NRF.findDevices(function(devices) {
  if (devices.length>0)
  {
    print("I found you :\n\r ");
    for(var i=0;i<devices.length;i++)
  {
    
    var time = (new Date()).toString();
    var rssi = devices[i].rssi;
    var MAC = devices[i].id;
    var name = devices[i].name;
    var manufacturer = devices[i].manufacturer;
    print (
         + " " +   time
         + " " +   MAC
         + " " +   rssi
         + " " +   name
         + "  " + manufacturer
    );
    
  } }
  LED1.write(true);    
 print ("**************************");               
}, 1000);},5000);

I can see devices found (none of them is my phone...)

I found you :

**************************

everything is on the desk maybe 10 cm from the device
the samsung phone bluetooth is open
how could it be ?
did I miss something in the code?

Thanks ,

Thanks!

great
thank you
I think you can post the code you post here as an easy to understand example
or even first code jsut flahs it
much more easy to understand ....

so see I understand it correct:

NRF.setAdvertising([
require("ble_eddystone").get("http://www­.david.com"),
{

//this part is all the data I want to show using Hex , 
// can take examples from here https://www.bluetooth.com/specifications­/gatt/characteristics/ - //right?
   0x180F : [NRF.getBattery()],
   0x1809 : [Math.round(E.getTemperature())]
  } 
],
//this is the default setting I can cahnge - right ? this is the only setting I can change from here 
{
   name  : "David",
   showName: true,
   discoverable : true,
   connectable : false,
   scannable : true,
   interval:100
});

so now:
I can see the device in bluetooth normal scan (see the name only and can't connect to it because of connectable : false)
I can see the data from "NRF-connect". which is what I want

Thank you so so much for this!

---

1. I'm tryin to play with this , and send more data
   just for the test I want to test this Hex(Got this from https://www.bluetooth.com/specifications­/gatt/characteristics/)
   
   

Age org.bluetooth.characteristic.age 0x2A80 GSS
and add this to the code:

  {//here I put the HEX data -https://www.bluetooth.com/specification­s/gatt/characteristics/
   0x180F : [NRF.getBattery()],
   0x1809 : [Math.round(E.getTemperature())],
   0x2A80 : "15"
  } 

in the NRF I can see battery\temp but not age -jsut Service Data without name - why?
just 20x2A80 0x31 0x35 (which is 15)
is it standart?

1. also can I set the time of the ble_eddystone for showing 2 websites?
   I did this

   require("ble_eddystone").get("http://www­.david1.com"),
   require("ble_eddystone").get("http://www­.Danny1.com"),
   

   if I want to make 1 min for website1 and 2 min for website 2?
   and meanwhile it will send data every 1 sec ?
   or I need to write a more complicated code for this ?

2. also the battery shown 3%
   is it because I'm connecting using USB to the V+ (5V) and not to the battery input?
   can I know what the voltage I'm using ? beacuse I saw it can be power on

   will work off of 2.5 to 16 volts
   can I measure the input?

Thanks,
