Lopy-wlan not appearing after stoppinig mqtt example

[mkbenon]

I started going through the Lopy examples. I was able to upgrade the firmware to the latest release as of June 2017. I was able to sync files through the Atom plug in of Pymakr. I was also able to upload files on FileZilla and see output from Tera Term.

However, after running the mqtt example from here, and getting the output as expected, I am not able to see the Lopy-wlan after stopping the mqtt example main.py application by pressing CTRL-C in Tera Term. I am therefore not able to sync or update the main.py application.

How do I get the Lopy-wlan back?

By default LoPy's WLAN is AP mode (WLAN.AP) and MQTT example script change that mode to Station/Client mode (WLAN.STA).

So if you want LoPy-WLAN back you must simply change to WLAN.AP mode.

There is also mixed mode WLAN.STA_AP.

WLAN.STA_AP

Thank you so much! That worked!
In my serial connection, I typed, "wlan.init(mode=WLAN.AP)" after importing network.
Thanks!

@mkbenon You're welcome, I just gave you some hints, glad that you manage yourself (best learning method). :o)

Also please note that MQTT example script changes WLAN antenna mode for external (WLAN.EXT_ANT). If your LoPy setup has the external antenna - that's OK, but if not you should use default internal antenna (WLAN.INT_ANT).
