i need help how to read blynk_token from portal and assign to blynk.config or blynk.begin?

thanks

hi, look in the FS example
https://github.com/tzapu/WiFiManager/blob/master/examples/AutoConnectWithFSParameters/AutoConnectWithFSParameters.ino

 blynk_token = custom_blynk_token.getValue();

thanks for your fast response

blynk_token = custom_blynk_token.getValue();

Blynk.config(blynk_token);
//Blynk.begin(blynk_token);
Serial.println(blynk_token);

if I use Blynk config no error on compile but esp is not on network
but if i use Blynk begin, it cant compile

because blynk_token is const char but Blynk.begin need char array.
how to convert const char to char array

Dear Tzapu,

I need to use your parameter blynk token in my sketch but it is not work.

The goal is ESP 12E can be reset and connect to new wifi and new token without upload sketch again and again.

Please help

Yes I did,

After input SSID and password and blynk auth token at portal, then your library wifi manager use the ssid and password to connect to wifi network, after connected and then I use blynk auth token from portal with syntax like this
blynk_token = custom_blynk_token.getValue();

And then
Blynk.config(blynk_token). But it is not work.

You can see from my sketch below.

and after, does Blynk.run say connecting or anything?
if you put Blynk.config("419f17ecfe0a45ba88580f6977cb038"); directly as a test, does it work?
