khoih-prog / BlynkGSM_Manager

Simple GSM shield Manager for Blynk and ESP32 / ESP8266 boards, with or without SSL, configuration data saved in SPIFFS / EEPROM. This library enables user to include both Blynk GSM/GPRS and WiFi libraries in one sketch, run both WiFi and GSM/GPRS simultaneously, or select one to use at runtime after reboot.

Không thể gửi giá trị cảm biến về blynk khi sử dụng GPRS #6

Closed mrrynk closed 4 years ago

mrrynk commented 4 years ago

Tôi đang dùng T-CALL và SHT30 nhưng không thể gửi giá trị SHT30 về Blynk khi sử dụng GPRS, Khi sử dụng WIFI thì mọi thứ hoạt động bình thường.

BlynkGsmManager - Cannot send sensor value to blynk while connected to GPRS

I use the SHT30 sensor to measure the temperature and humidity but having trouble connecting to the GPRS, the ESP does not send value to Blynk. Wifi is stable.
