Hi All,
i am tying to get location from my particle electron (GSM), Asks the Cellular module for info about the tower it’s connected to. and yea i can get and view data in particle console like, id, mcc and mnc but i want to view this data on map, i tried to send these data to Ubidots but seems something wrong,
your advice and help please
thank you
Maj
Without seeing some code, there's nothing we can do really.
You might also want to show how you configured Ubidots.
What have you tried to debug so far?
Hi Moors, thank you for your reply, this code is used to get data location as i mentioned like cellular ID, mcc and mnc and i added few code lines to demonstrate the location in ubidots map but i cant, please have a look and let me know if you need more info
