Or what happens if you move GS2200M near the Wi-Fi router?

Could you tell me a product name of the Wi-Fi router? And the issue might be mitigated if you change Wi-Fi router settings.

("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. > > On 2020/02/11 1:20, "Takashi Yamamoto" <yamam...@midokura.com.INVALID> wrote: > > Thank you. > It looks like the same board as I have. > For me I feel it works 30% of the time. > I wonder what's the difference. > > On Tue, Feb 11, 2020, 01:10 Alin Jerpelea <jerpe...@gmail.com> wrote: > > > I am using this one > > > > https://www.chip1stop.com/SWE/en/product/detail?partId=IDYC-0000001&mpn=iS110B&keyword=spresense&zaikoFlg=false&partSameFlg=false > > > > On Mon, Feb 10, 2020 at 5:06 PM Xiang Xiao <xiaoxiang781...@gmail.com> > > wrote: > > > > > Ubuntu 18.04 run on VirtualBox with NAT.
