PHP code test

require_once('easybitcoin.php');
$bitcoin = new Bitcoin('bitcoinrpc','xxxxxxxxxxxxxxxxxx','localhost','8332');
$bitcoin->settxfee(0.00020000);
$result[0] = $bitcoin->getinfo();
$result[1] = $bitcoin->sendfrom('kernel','bbbbbbbbbbbbbbbbbbbbbb',0.00200000);
$bitcoin->dump($result);

Does the problem exist in Bitcoin Core? (i.e. the GUI debug window or rpc interface)

Also, what version of Bitcoin Core?

Yes problem exist in Bitcoin Core , Bitcoin Core 0.13.1

You're aware that settxfee sets the fee per kilobyte? The size of a transaction in bytes isn't know in advance. You can use the raw transaction API to see constructed transactions before broadcasting them, if you want more control.

If I want a fee high priority transaction , I want sample setting

Sorry, my english is not good

Try to use

1. estimatesmartfee <blocktarget> (2 if you want fast confirmation)
2. createrawtransaction [] {'addr':<amount>}
3. fundrawtransaction <hex> {'feeRate': <feerate_per_kb_form_step1>}
4. optionally: check the fee
5. singrawtransaction <hex>
6. sendrawtransaction <hex>

This is the preferred way that allows one to better control fees, etc.

Closing. This probably belongs to http://bitcoin.stackexchange.com (or similar).

This could also be #9466, as the fee per kb of the transaction does not match with settxfee.

Cannot send by account ?
