[Ethereum] Can not send eth on Ropsten using Infura node


I am trying to send some test ether on Ropsten network using Infura but I can not make a transaction. Code works locally with testrpc but not with Infura

var Web3 = require('web3');
var util = require('ethereumjs-util');
var tx = require('ethereumjs-tx');
var lightwallet = require('eth-lightwallet');
var txutils = lightwallet.txutils;

var web3 = new Web3(
    new Web3.providers.HttpProvider('https://ropsten.infura.io/<token>')
    //new Web3.providers.HttpProvider('http://localhost:8545')

var address = '0xadaD904F70ec8323fEd1734614d78D2145222322';
var address2 = '0x5858599f16c46fa33238313A412eE9f0491EBef3';
var key = '<KEY>';
var key2 = '<KEY>';
var amount = web3.toWei(1, "ether");
var balance = web3.eth.getBalance(address);

var value = web3.fromWei(balance, 'ether');


function sendRaw(rawTx) {
    var privateKey = new Buffer(key, 'hex');
    var transaction = new tx(rawTx);
    var serializedTx = transaction.serialize().toString('hex');
        '0x' + serializedTx, function(err, result) {
            if(err) {
            } else {

var rawTx = {
    nonce: web3.toHex(web3.eth.getTransactionCount(address)),
    gasLimit: web3.toHex(21000),
    to: address2,
    value: web3.toHex(web3.toBigNumber(amount))



As you can notice I am logging ether on address but no matter how many times I send the transaction it stays eq to 1eth.

Any ideas what I am doing wrong?

This looks mostly correct, but there are a couple optional tx parameters that might make the difference:

  // EIP 155 chainId - mainnet: 1, ropsten: 3
  chainId: 3,
  gasPrice: "0x9184e72a000", // 10000000000000

Also, the nonce may need to be converted to hexadecimal. The getTransactionCount method returns a javascript number, so you might need to convert that to hex first.

I'd recommend also logging the parameters before you send it out. If you're connecting to a node that is not synchronized, your nonce could be wrong, and that would also fail these transactions.

I see you got one tx out, so that makes me think a wrong nonce could be blocking you. https://testnet.etherscan.io/tx/0x17c6e7e318a181cc729207ebe2bc203b4df71657b845aaf551892f20de42bc62
