I used a lora for sending datas constantly, and I recieved datas in espruion.

I recieve data like this:
```
lora.on('data', function (data) {
  console.log(data);
});
```
but I can't get the whole datas, just one character。
I send 'abcccc',
but console.log always print a,b,c,c,c,c one by one.
How do I get the whole data?

'I recieved datas in espruion'

Did you mean 'Espruino?'

Hi @user109783,

Ref L1 lora.on As there isn't a 'lora' object listed within the Espruino Reference,

http://www.espruino.com/Reference#lora
http://www.espruino.com/SX127x#line=27,28,36

it is too difficult to comprehend what is going on here.

Lets start with the basics:

Post the result of process.env so we are able to better understand the environment.

'I send 'abcccc''

Please post the sending code.

'I used a lora for sending'

Which device? (lora) and Espruino

Which tutorial is being worked from? Please post link.

Hi,

How do I get the whole data?
- well how do you define whole data?
- can you define a char as end marker like .?
If yes, then just concat until char == '.'

Edit: check http://www.espruino.com/USART sample Serial1.on('data', function (data) {}

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
