WiFi v0.5

[b4sh]

Now, new background mode not work for me, endless scanning. Switching wifi mode to "3" also not work. I have 16 wifi networks in range (urban area), maybe this matter. Code after if (index >= 0) { // some network was found (.......) not exec - index is always "-1". curidx also is always "-1".

Hmm. I unfortunately cannot reproduce this (I have less then 16 wifi networks here, but this shouldn't be a problem...).

Can you copy the console output from Arduino IDE (starting with the line "x networks in network.txt" and until "Running main loop.")?

maybe spaces in network SSID "UPC Wi-Free" cause problem?

[dl9rdz]

Very strange.

In most recent version in the "devel" branch I have added a bit more debug output. Maybe you can retry with that (only with wifi=3, the background mode with wifi=1 has little debug output)

The expected output is something like: 23:34:27.046 -> 2 networks in networks.txt 23:34:27.046 -> 23:34:27.046 -> RDZsonde: RDZsonde 23:34:27.046 -> DinoGast: Schokolade [skipping some lines] 23:34:29.928 -> Completed scan for access points 23:34:29.928 -> Network name: Dinosauro 23:34:29.965 -> Signal strength: -56 23:34:29.965 -> MAC address: E0:28:6D:4E:FE:AC 23:34:29.965 -> Encryption type: WPA_WPA2_PSK 23:34:29.965 -> ----------------------- 23:34:29.965 -> No match: 'Dinosauro' vs 'RDZsonde' 23:34:29.965 -> No match: 'Dinosauro' vs 'DinoGast' 23:34:29.965 -> Network name: DinoGast 23:34:29.965 -> Signal strength: -56 23:34:29.965 -> MAC address: E2:28:6D:4E:FE:AC 23:34:29.965 -> Encryption type: WPA2_PSK 23:34:29.965 -> ----------------------- 23:34:29.965 -> No match: 'DinoGast' vs 'RDZsonde' 23:34:29.965 -> Match found at scan entry 1, config network 1 23:34:29.965 -> Network name: LEDnetB94524 23:34:30.002 -> Signal strength: -79 23:34:30.002 -> MAC address: 62:01:94:B9:45:24 23:34:30.002 -> Encryption type: Open 23:34:30.002 -> ----------------------- 23:34:30.002 -> No match: 'LEDnetB94524' vs 'RDZsonde' 23:34:30.002 -> No match: 'LEDnetB94524' vs 'DinoGast' 23:34:30.002 -> Connecting to: DinoGast

So for every network found by scan, you should get some lines with "No match..." or "Match found..", and there should be one match, followed by "Connected to:" the matching network

Well, thanks... but still, I am somewhat clueless. This part of the code is quite simple:

if (strcmp(id, networks[i].id.c_str()) == 0) {
      Serial.printf("Match for %s at %d\n", id, i);
      return i;
}
Serial.printf("No match: '%s' vs '%s'\n", id, networks[i].id.c_str());

Now in your output, both strings look identical, and strcmp should return 0 in that case, and not print "No match".

Maybe one of your hyphens (in your SSID? in network.txt?) is not an iso8859-1 hyphen but some other utf-8 hyphen? And gets magically converted to an iso8859-1 hyphen when copy&pasting the text to this web page? Or one of the two contains some other non-printable character?

Most recent devel contains even more debug messages... maybe this helps. Otherwise I have no more ideas.

[b4sh]

I found the reason - line endings. My file somehow changed to Windows CR LF, after change to Unix LF everything works.

Thanks for your assist. It is a pity that I did not get it earlier. This is worth mentioning in the readme file. It may save some time to others. :)

Now i have ANSI encoding with Unix LF line endings.

[dl9rdz]

Also found some minor C++ errors that could possibly cause network problems. Fixed in the latest release.

[ok2it]

I confirm All Works on 64 plus Network Overhere

[dl9rdz]

The latest devel update makes all data files tolerant to line endings, so CR LF should be fine now instead of just LF.
