hang with --ble : waiting for <coroutine object BleakClient.write_gatt_char

[edsantiago]

Querying my nodes from my Gentoo laptop, meshtastic commands never terminate. They do produce the desired output (info, export-config) but I have to check for the file from another term window, then ^C the meshtastic process.

$ meshtastic --debug --ble edr2_1e23 --info >info
...does the pause thing...
....then lots and lots of output, as expected, which I'll skip...
