# How do you bech32 encode a string on the card ?
|
|
|
|
The LNURLw that comes from the bolt card is not bech32 encoded.
|
|
It uses [LUD-17](https://github.com/fiatjaf/lnurl-rfc/blob/luds/17.md).

# How do I generate a random key value ?
|
|

This will give you a new 128 bit random key as a 32 character hex value.
|
|
`$ hexdump -vn16 -e'4/4 "%08x" 1 "\n"' /dev/random`

# Why do I get a payment failure with NO_ROUTE ?
|
|
|
|
This is due to your payment lightning node not finding a route to the merchant lightning node.
|
|
It may help to open well funded channels to other well connected nodes.
|
|
It may also help to increase your maximum network fee in your service variables, **FEE_LIMIT_SAT** / **FEE_LIMIT_PERCENT** .
|
|
It can be useful to test paying invoices directly from your lightning node.

# Why do my payments take so long ?
|
|
|
|
This is due to the time taken for your payment lightning node to find a route.
|
|
It can be improved by opening channels using clearnet rather than on the tor network.
|
|
It may also help to improve your lightning node hardware or software setup.

It can be useful to test paying invoices directly from your lightning node.

# Can I use the same lightning node for the customer (bolt card) and the merchant (POS) ?
|
|
|
|
When tested with LND in Nov 2022, the paying (customer, bolt card) lightning node must be a separate instance to the invoicing (merchant, POS) lightning node.

# I get a 6982 error when trying to program a blank card
|
|
|
|
A 6982 error is is known to happen after trying to use a 'blank' card which has been wiped with the CoinCorner customer app (July 2023) and happens because the card settings have not been cleared down correctly. It can also happen where a card is removed partway through programming (which can take a few seconds) or where the mobile device does not complete programming due to being in a low battery situation.
|
|
The card settings can be fixed by using the 'Bolt Card NFC Card Creator' app. The card will then be blank and usable again.
