Hello,

I have a hw.1 and use it with electrum, it works fine overall,
but now I have an address where I can't send anything from.

It is this one: 1Jmv13FgTW1xeGGvATt2EP142efBq473bA
The coins on this address came from a greenaddress wallet (address starts with 3)
I've seen something about p2sh todo in the btchip plugin, not sure if relevant
because  I am not really a programmer, but maybe that could be the problem?
If this is a btchip limitation it would suck, or is it an electrum bug?

I added a "print tx" at the point where it fails and the transaction looks ok to me,
I can load it with electrum and look at it, but it is obv unsigned

Selecting send from other addresses works fine so it is no big deal,
but if this is a bug it would be good if it could be fixed

Code:

  File "/home/user/electrum-git/electrum/gui/qt/util.py", line 37, in run
    self.result = self.run_task()
  File "/home/user/electrum-git/electrum/gui/qt/main_window.py", line 1156, in sign_thread
    self.wallet.sign_transaction(tx, password)
  File "/home/user/electrum-git/electrum/plugins/btchipwallet.py", line 330, in sign_transaction
    raise BaseException(tx.error)
BaseException: byte must be in range(0, 256)

There shouldn't be an issue to use those funds, so I'm afraid the answer lies probably in the middle with a BTChip Python bug dealing with long input scripts (around here) . I'll test that, might take a few days due to long trips.

shipping is fast, but manufacturing is done on demand (this is one of my new tests  ) so it'll ship end of next week, as stated on the website.

I placed a couple of orders on your store. Am I supposed to get a confirmation email after I pay?

Hi

It's ok, you don't get an email confirmation.

TX #2 is ok and confirmed.

TX #1 is apparently not going to me

You are right, #1 is not yours, I made a mistake, but now that I know I won't get an email confirm, I won't bother you with the second order tx I.D.

Have a good weekend, I'll wait patiently for my orders.

Cheers

This should have been addressed in my latest updates. Can you pull btchip-python and retest ?

did the previous version work ?

(just rechecked, it works fine on Linux, unsurprisingly)

[AussieHash]

@btchip is there a way to generate the xpub key for a specific path using any of the command line APIs ? In particular I am trying to manually sign "Coinkite" with "0'/0/0" to test their multisig, but I need the xpub key for that path. Thanks.

yes, we and BitMEX recently added this in better Coinkite cosigning integration scripts - have a look at https://github.com/BitMEX/btchip-signing-tools and  https://github.com/BitMEX/btchip-signing-tools/blob/master/utils/getKey.py for what you need

I didn't do anything. I  couldn't install the firmware which I downloaded from hardwarewallet website, so I chose windows to download and install automatically and it did. I already installed BTChip and electrum. But when I am trying to open, it isn't coming.

P.S. I haven't installed linux on my system yet, probably, I will install on Saturday or Sunday. Anything I can do before that to work with Win7?

AND, thanks for 2 for 1 offer!

I'd need to retest on Windows at some point, there are a lot of reasons why accessing the dongle from Python could fail.
