@torntrousers Please, use samples/boards/esp32/wifi_station as reference.

[torntrousers]

Thanks @sylvioalves . I've got that to run but it does not seem to connect. I've tried putting in the incorrect password and th elog is the same. Is there some thing I can do to debug what is happening?

[sylvioalves]

@torntrousers Have you set that at the prj.conf file? What is the wifi security type?

[torntrousers]

Yes, I found CONFIG_ESP32_WIFI_SSID and CONFIG_ESP32_WIFI_PASSWORD in zephyrproject\zephyr\samples\boards\esp32\wifi_station\prj.conf and set those for my Wifi access point. I haven;t changed anything else , so whatever the default security type is?

[torntrousers]

Any ideas @sylvioalves ?

[sylvioalves]

@torntrousers I checked that with latest main branch and it worked. Have you performed west update and west espressif update in your env? Is your wifi network configured as WPA or WPA2?

[torntrousers]

Thanks @sylvioalves . Network is WPA2-Personal (according to WIndows Network Properties). The ESP32 connects to it ok with the ESP32 Arduino framework.

I had not run those west commands, I have now but after rebuilding and flashing there is no difference.

@torntrousers Is the file prj.conf modified (except for for ssid and pass)?

[torntrousers]

@sylvioalves no changes other than the ssid/password. It looks like this:

CONFIG_HEAP_MEM_POOL_SIZE=98304

CONFIG_NETWORKING=y
CONFIG_NET_L2_ETHERNET=y

[torntrousers]

@sylvioalves I've tried this with my Wifi access point and also using a hotspot on my Android phone (also WPA2-Personal). Neither work with Zephyr but both work with ESP32 Arduino environment.

To workout if its some problem with my Zephyr install/build how about would it be possible for you to build the sample and send it to me so I can try you binary? My hotspot ssid/password is Balloon1/qaz123456.

Or what is some other way to debug the problem?

[sylvioalves]

@torntrousers I have just tested with my phone as well and it worked with same credentials.

Find the bin file at zephyr.zip.

Hum, You have been working on Windows, right? I'll try in Windows as well.

@sylvioalves Your binary does not work for me, so that is interesting.

First, just to verify that I'm trying it correctly, I get your binary, copy it to zephyrproject\zephyr\build\zephyr overwriting my local zephyr.bin which is there, and then do west flash --esp-device COM4, is that correct?

So I guess the next is for you to try the binary that my environment generates, zephyr.zip.

I wondered if you'd actually used the correct ssid/password so looked in the binary and I can see those there in yours, so it looks good:

xxd -s 664 -l 45  build/zephyr/zephyr.bin
00000298: 4261 6c6c 6f6f 6e31 0000 0000 0000 0000  Balloon1........
000002a8: 0000 0000 0000 0000 0000 0000 0000 0000  ................
000002b8: 7161 7a31 3233 3435 3600 0000 00         qaz123456....

Then I wondered how my built one one compares to yours - they are exactly the same size, so that seems good:

ls -al build/zephyr/zephyr.bin
-rwxrwxrwx 1 ant ant 383392 Jun 22  2021 build/zephyr/zephyr.bin
ant@CQ-LAP-000001:/mnt/c/Users/Administrator.CQ-LAP-000001/zephyrproject/zephyr$ ls -al ../zephyr2.bin
-rwxrwxrwx 1 ant ant 383392 Jun 22  2021 ../zephyr2.bin

and a diff on them is is tiny compared to the size of the files -

xxd ../zephyr2.bin > f1
ant@CQ-LAP-000001:/mnt/c/Users/Administrator.CQ-LAP-000001/zephyrproject/zephyr$ xxd build/zephyr/zephyr.bin  >f2

The very first bit of the diff is intersting - v2.6.0-385-g2d3195c8a2e2 in mine vs v2.6.0-420-ge62c3c533a37 in yours. You have a newer version of something than me - do you recognize what that is a version of ? Is it an ESP32 thing, the IDF or something?

[torntrousers]

Oh, its Zephyr isn't it - I'm on a older build than you. How do I update that?

[sylvioalves]

I think it is something related to the board config itself. Let me check, I'll get back to you.. BTW, do you have a slack account?

[torntrousers]

@sylvioalves , I have just joined the Zephyr slack so yes I have an account now.

[torntrousers]

Hi @sylvioalves , any ideas yet? Did that binary built on my system work for you on yours?

[torntrousers]

With help from @sylvioalves on slack this has been resolved - it was the Heltec board itself and using a different ESP32 module and it all works fine. Not sure what the problem is with the Heltec board as it works fine with the Arduinio/ESP32 environment, but that can be for another day.
