1 year ago Hi @pablopeu I'm trying to work with mathworks ThingSpeak IOT library, but with ESP32 seems not working also the included example WriteSingleFieldSecure.ino as is (using HTTPS).
No problem with HTTP connection indeed, even togheter with AsyncTelegram2, but using two distinct client (WiFiClientSecure for AsyncTelegram2 and WiFiClient for ThingSpeak).

1 year ago Hi @cotestatnt thanks for the reply.
Based on your suggestion to use nonsecure thingspeak as this example works, here is the code I made merging you echobot code (sans the your public channel update and LED) with the thingspeak example. Both of these run alone work as expected, but when merged only thingspeak. The telegram bot is not updated but is properly detected. Not even the welcome message is sent.
Testing on esp32
I'm sure botching something LOL but can't see it.
`/* WriteMultipleFields Library Example
Description: Writes values to fields 1,2,3,4 and status in a single ThingSpeak update every 20 seconds over secured HTTPS connection.
Hardware: ESP32 based boards
!!! IMPORTANT - Modify the secrets.h file for this project with your network connection and ThingSpeak channel details. !!!
Note:
This example is written for a network using WPA encryption. For WEP or WPA, change the WiFi.begin() call accordingly.

1 year ago small update, if I change #define USE_CLIENTSSL true to false I get the welcome message, but not the echo replacing myBot.sendMessage(msg, msg.text); by: myBot.sendTo(userid, msg.text); this also doesnt work:
but sending a message outside if (myBot.getNewMessage(msg)) { like: myBot.sendTo(userid, "test"); works as expected

1 year ago it was the delay(20000)... replaced it with a timer and received all the replies at once LOL
here is the code, I'm sure will help someone else:

Hi, I'm having a hard time trying to merge two projects into one, take for example the lightbot example in the library, and another example, in my case, the thingspeak IOT library (https://github.com/mathworks/thingspeak-arduino) This library allows making HTTP or HTTPS connections to update sensor values on the Thingspeak site.
Is it possible for AsyncTelegram2 to connect and update while in the same app updating the other library? Tried HTTP and HTTPS in the thingspeak library and either AT2 doesn't connect or TS fails at updating.
Thanks
