for now, just a mqtt client.
(i know gs2200m has some mqtt functionalities. but i'm not going to use it)

i'm using station mode. connecting to the existing AP. using WPA2.
it sometimes work, sometimes not.
when it doesn't work, usually AT+WA gets ERROR response. ("WLAN
CONNECT ERROR" if you raise log level of gs2200m)
it's somehow mitigated by the following change.
https://github.com/apache/incubator-nuttx-apps/commit/2f4b309b1b9faad87788d0668617b07bcfbca305
occasiionally AT+WA even timeouts (SPI_TIMEOUT) and it causes
assertion failures in the following AT commands because the driver
and gs2200m are now out of sync. i guess the driver should reset the
chip after giving up waiting for it.
even when it's working, tcp connections are occasionally dropped.
usually it recovers if i tcp-reconnect. i haven't investigated this
symptom.
