E32-DTU for chatting with android to windows or linux or Android to Android etc.. #14

Open theck32 opened 2 years ago

theck32 commented 2 years ago

Would it be possible to create a setup to chat between two arduino or two nodemcu esp8266 or just two android phones connect with an OTG cable and serial port to usb adapter and a lora E32-DTU to communicate between the two without the need for servers? It works with my two E32-DTU modules connected with an OTG cable on android but I have to use a terminal and it's not chat friendly! The modules I am talking about here are E32-DTU lora at 1 watt and which already have an RS232 and RS485 output and its own power supply! I would be very happy to use these modules to discuss, I would like to know if my ideas are feasible, good or simply impossible! thank you in advance and sorry for my bad english I speak in french 😉 (And even Android with OTG cable and RS232 to usb adapter to speak with a user on windows or linux! I know it's 100% possible via a terminal but I'm looking more for an application like you present it in your github)

Although it is definitely possible to connect a LoRA module directly to your phone, you wouldn't be able to use the methods described in this repo to create an IP network between two Android phones, unless you root then. You'll still be able to access the serial device and send raw packets.

As for communicating between two Arduino devices: There may be someone who has already done this, but you would have to communicate with the AX.25 protocol.

I have in my possession two Ebyte n114 modules also which precisely transfer the RS232 and RS485 ports in IP or on MQTT, so I can with that transfer my RS232 connectors from lora to IP directly and use the application written here, right?

If I express myself better I give an example I connect my E32-DTU modules in RS232 to my Ebyte NB114 modules which is designed to receive RS232 connections and transfer them to an IP in this way my Lora E32-DTU Radio modules would have a IP address instead of an RS232 output so it would be possible to use it with your technique, right?
