Hello. Subject. It is necessary to make wireless speakers out of ordinary speakers. I've never been interested in this myself, I'm looking for advice. Thanks in advance

Answer 1

SELECT * FROM `wallets`
LEFT JOIN `wallet_address` 
ON (wallets.id = wallet_address.wallet_id) 
WHERE EXISTS (SELECT user_id
              FROM wallet_address AS t1
              WHERE t1.user_id=1)

. Can there really be several users per wallet?
Do you need to withdraw wallets linked to each user or is it just one time? In the second case JOIN is not needed

In any store, a bluetooth adapter with a jack connector.
If you want better, then take care of the presence of aptx from both ends.
