* Upgrade all submodules * Use stock standard_setup and remove our version Switch no longer relies on Pubsub argument * Fix peerId * Add reference to WakuRelay in WakuNode * Use WakuRelay ref directly instead of via switch * Tweak standard switch sig * Fix start_network peerid * Import nim-libp2p utils test * Use WakuRelay in test utils * Fix utils imports * Tweak * Fix trigger self test * Disable broken filter test * Fix and amend logscope topics * Make subscribe calls async to use await * Add debug stuff to nimble file * Await for subscribe content * Sleeping in tests * Local checkout fixes * XXX: Try to use .PubSub on WakuRelay * Revert "XXX: Try to use .PubSub on WakuRelay" This reverts commit 3a3139e4cfbb5ae9500fd30b2e79c676ccc4a53b. * Only using gossip seems to work Subscribe for floodsub broken * Fix await in examples * Get rid of double publish, still need sleep
