This article mainly explains "how to send and receive Nokia AT instructions". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to send and receive Nokia AT instructions.

In the past, I was very confused that the hyperterminal included in Windows could not send and receive AT commands from Nokia phones, so I always thought that Nokia phones could not use AT commands.

Today, I used Serial Monitor to re-monitor the communication process of playing with my mobile phone, and found that as long as you set RTS=ON and DTR=ON, you can send and receive AT commands. HyperTerminal only sets DTR to ON when connecting, but RTS doesn't, which is why it can't connect.

In addition, RTS=OFF and DTR=OFF are required when sending and receiving FBUS commands. Ha ha, it seems that the serial port is quite fun:)

Have time to write a more complete and easy-to-use serial port tool.

At this point, I believe you have a deeper understanding of "how to send and receive Nokia AT instructions". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
