Telegram and ESPNOW problems

[thefly0]

Hello, can anyone help in suggesting a code, if possibile, to run simultaneously ESPNOW (to receive data periodically from my sensor) and telegram to read data from internet. I'm using and ESP32D (node32s). At the moment the only solution I found is disconnecting WiFi when not checking Telegram bot. Below I attached my code. thanks in advance Stefano

Please request help.

• it would be possible to use the telegram bot using esp8266 and espnow. Idea to make a small network (one room) with ESPNOW and interconnect in a corridor to other rooms, via RS485, a small central ESP8266 via Telegram Bot. Thanks AlvaroLuiz2@yahoo.com.br
