Hi Mark,<br>
<br>
Yes, specifying the AP works fine (ignoring the crash I got when
changing APs on the fly). I certainly don't expect a scan to pick
up a hidden AP, but I do think that connecting to a hidden one which
has been configured should work the same as a configured one that is
in full peacock mode with its beacons. Both phones and laptops can;
that's what probe frames are for. <br>
<br>
Conversely (haven't checked this), we should not be connecting
promiscuously to an AP that has not been configured. Way too likely
to hit a Hotspot that requires a login / EULA Acceptance button, and
thus breaking a perfectly good, if slow, LTE connection in favor of
a hot WiFi connection that goes no where. Not to mention the
security angle.<br>
<br>
Is the promiscuous connect loop driven from the results of the scan,
or by walking / probing the list of configured SSIDs? It should be
the later.<br>

<div>You won’t be able to see it in the scan, and won’t be able to

specify it.</div>

<div>So long as you are running latest firmware and diff sdkconfig
and sdkconfig.defaults is not too far off (pay attention to
Bluetooth), it should work.</div>

Ah, the proverbial "heap of trouble"... {ahem} Sorry.
Perhaps something to tune later, or do we need to adjust
things now? <br>
<br>
So, the original issue - automatically connecting to a hidden
AP- is not related. It's not a showstopper for me since I
have the dongle, but could be important for some (e.g. WiFi at
home hidden, work is open). It appears that the wifi scan
code is somewhere in the ELF library set. Is it worth trying
to dig into it?<br>

<pre wrap="">Greg,
The crash was in the "new" operation because you ran out of heap
space.

<pre wrap="">Hi all,
Is there an easy way to enable the wifi code to connect to an SSID that's known
(configured) but hidden, without directly telling it to? i.e., using 'wifi mode
client' by itself (no SSID specified)?
Some of the places I want to connect to are visible (seen in a scan), but the home
network is hidden. If it helps, running a scan within earshot of the home network
only burps up an error 'wifi: incorrect scan type: 1073583304'.

p.s. Possibly related, I have the module in my Roadster, connected to the V2 server
via WiFi through a SyncUp Drive OBDII dongle that's being driven by the OBD2ECU
engine. The SyncUp's WiFi hotspot is visible, and I have a startup script that gets
everything going, and the OVMS module auto connects through it. I just tried forcing
the connection over to the home network (wifi mode client gregnet) and after switching
networks and reconnecting to the V2 server, crashed and rebooted (whereupon it
reconnected through the dongle's network). Any ideas?
