Unable to connect via Bluetooth using datalogger (one +)

Postby topema » Tue Aug 14, 2018 8:26 pm

Hello Everyone!!

I am trying to connect via bluetooth to freematics one plus and I am not able to do it. I have followed, step by step, the developers guide of the freematics one page, uploading the datalogger sketch from firmware_v5 to one plus using platformiO and I can't activate the bluetooth device, I tried to connect to the device with an android (BleTerm) with an iOs (LightBlue) and with my computer and I can't even detect the device, it seems that the itis not generating the signal and I don't know how to solve this.

How can I do to establish a bluetooth connection with the device to read the outputs? I modified the datalogger's config.h and I didn't achieve it. I looked in the entire firmware_v5 some line of code referring to the bluetooth and there is not even one.

I don't know if it is a problem with the device itself, the device's wifi works and I can read the datalogger's output printed on the sd card.

I am very newby using arduino and I would love not to touch much the freematics sketches. I am using freematics one plus, connected to an OBD-II emulator. please I need help!!

Currently Bluetooth is not brought up in the code of datalogger. You can use Arduino BLE library and example sketches to test.
