Light Bot Problem 2

[muk3shb]

How can we implement TOTP on our bot ? For that there is TOTP library in Arduino and then it is saying to generate "hmac" key. or how can we limit the IP access like telegram_ip_lower or telegram_ip_upper are there any such function under Async library to limit the IP's ?

Next, can we limit the ESP32 board to sepcific IP's ? as telegram bots can be accessed by any user around the world hence, all we can do is to limit the IP access or is there any other method ?

Hi, if you look at the examples, in the setup you find this:

int64_t user id = 123456789;
myBot.sendTo (userid, welcome_msg);

this means that only the telegam user with id = 123456789 will be able to receive replies from your bot. Similarly, you can do the same by telling your bot to receive and process responses only from one or more selected telegram ID .

Hello

Thankyou So much!! I found that code on the example and with little changes, it is working!! i have not changed anything just very minute changes. There are no errors but the message is continuously generating. Here is the code..

// i am reverifying the chatid by using simple operator and it is working!! but the bot is continuosly generating the message. the code that i have mentioned will work fine

#define USE_CLIENTSSL false

@muk3shb please use code tag <> for sketches.

I've replied in the other issue opened by you, but it's not clear is this issue is the same or not.

Thankyou sir, This issue is the same and I was working on this and i thought that the Library should have some updated version and now here is the Latest Update by you. Thankyou So Much sir.

Ok, i'm going to close both issue then.

Thanks for your feedback
