Are there any examples of applications using 4G with mangoh Yellow not with Octave (if possible)?

The mangoh has the nc program which you can use to test tcp connectivity without writing any code. One think to keep in mind is that to make a tcp connection between two mangohs over cellular the target mangoh has to have an IP address which is visible to the originator.

Great thanks for the advice. Are there any existing examples or projects?

i think you can search how to use “nc” easily in google. If you want to implement in C program: [image] TCP Server-Client implementation in C - GeeksforGeeks A Computer Science portal for geeks. It contains well written, well thought and well explained computer science and programming a…

If I use tcp/ip should I add modem data control commands to transfer files other than SMS, as it is explained? In other words, is modem data control necessary to establish communication between 2 mangoh and send GPS coordinates or messages, if using tcp/ip?

You can use the cm command to establish data connection

Inside my code !? Or just from the terminal? I would like to edit ou code. I know cm command but just used that from terminal

Found it! Thanks. Forget my previous question

After reading the documentation, I araised 2 questions: are SMS commands only to communicate with a telephone (not adapted for communication between 2 mangoh) if I want to store data , should I use le_cfg_CreateWriteTxn or snprintf? I don’t really understand when it is adviced to use config tree? …

Sms can be applied to mangoh boards Normally config tree is for application setting

Ok get it! As I want to connect over LTE network, what is the IP address of my mangoh to use if I want to send messages using TCP/IP protocol. [image] 192.168.2.2 is only for USB connection right? Also, I cannot connect using this [image]
