hi sir,

I have just do the wiring of the device SIM7000 and ESP8266. But the issues is at the serial monitor it does not show the data of the device. I have enable the ESP8266+SIM7000 in the code but it still cannot get the data to check such AT commands and so on. I also follow your instructions wiring about SIM7000 "https://github.com/botletics/SIM7000-LTE-Shield/wiki/Pinouts" on ESP8266 except the temperature sensor.

Can you please guide me sir?

Thanks

Sorry sir but I try my best in this project.

If you are using the Botletics SIM7000 shield, please make sure you have a LiPo battery attached with the proper polarity (red wire should be on the left side of the connector when you plug it in). You should also verify the TX/RX pins physically and in the code for the ESP8266, because some boards label their pins differently.
