About to start work on a project with a particle electron. I am interested to know if anyone has been able to use the 3g connection on the electron with another connected device.
I don’t even know if this is possible but i want to have the electron connected to an RPI and it would be great to use the 3g connection on the electron to connect to the RPI over a vpn to run updates etc.
There are several ways to communicate between Electron and other devices.
e.g. the Electron can even pose as USB Mouse/Keyboard for a RPi, or talk via UART, I2C, SPI and countless other ways to the outside world.
But using the Electon as 3G modem for other devices seems less practical.
As you say the electron can be a lot of other things, but i was hoping to add the 3g modem capability as well. It seems a waste to use the electron to handle offboard things for the pi (ie reset,power up and down, reboot) then have to have a separate 3g modem to get internet access to the pi
Thanks again ScruffR, appreciate your input. I think I had read three of the four posts you linked.
The reason that i am investigating this is due to the fact that the project i am working on specifically uses a combination of a RPI and Electron already, the electron performs some “off pi” functions so that should the PI fall over there is some redundancy to the system.
However the project also calls for 3g connectivity on a PI, and it seems wasteful to have a 3g device (electron) already connected then need a second 3g modem and second sim and service just to enable data on the pi.
The master plan was to have the Electron setup to provide 3g internet to the pi as well as function as an “off-pi” device
