Hi, i am using the library in a ESP8466 and i am getting a soft reset every time the getGeoFromWiFi() is used but not always. I think this is because there are too many wifi ap's and it kind overflow some variable.
it can be possible?

I have the same problem

Hi, It is possible. Using HTTPS in ESP8266 makes free heap to go down to less than 20 kB during the request to Google.
I have quite a lot wifi networks around (around 20) but I've not tested the limit.
Another possibility is that WiFiClient library limit maximum content length, I guess this limit is about 1500 bytes.
Could you enable debug information and paste it here?

A possible work around could be limit the maximum number of networks filtering out less powerful ones.

Thanks

Hi, restart is due to watchdog. It may be because some code on your scketch. May you try plain example?

To enable debug you have to uncomment this line

gmag11 commented

I've built a new branch that limits number of networks to 20. Please test it:

Howdy gmag11! I have been trying to use the 20 wifi network limited branch, but I still get errors as previous posters have mentioned. Here is my debug info that I am getting. I am using an ESP8266 NodeMCU chip. Your help would be greatly appreciated. Thanks!

I hit same issue, its ESP8266 watchdog - waiting for response takes too long and you need to return control back to wifi stack.
Adding yield(); into waiting loop works for me:
// Wait for response while (millis() - timer < MAX_CONNECTION_TIMEOUT) { if (_client.available()){ break; } yield(); }

Santosh1971 commented

after putting yield(); the Watchdog reset stops but I am not getting lat long ... here is the debug output

Hi, I've added a couple yield() as of your comments. It is included on master branch on 90c9489
Thank you @hosek
