Freematics Forum

Hi everybody
I know there's a specific forum but posting is disabled, don't know why, maybe an admin can work this out and move the post.
Moving on, I'm using the telelogger firmware, no modifications, freematics hub, and wifi (which is a mobile phone doing tethering)
The Freematics device is able to connect and to send data but it disconnects after 60-90 seconds. No log in the serial. Never tries to reconnect.
Same behaviour if I have also a laptop connected to wifi, so I'm sure the network is properly working.

Any idea on how to troubleshoot?
Is there any flag in the code to turn on verbosity?
Is this a know behaviour?

Regards
Virgilio

So the serial output stops after disconnected? Can you give the final output contents?

Hi Stanley, thank you for your answer
No, the serial output continues, but there is no message about WIFI
And the device does not reconnect to hotspot. No matter how long I wait.

So my question is: should it automatically reconnect? is there any flag to control this behaviour?

I reproduced the error and this is what I get, every time

The Wire library (I2C) of ESP32 Arduino core is poorly implemented. I just rewrite the Freematics ONE+ library to avoid using Wire library and this proves to solve several stability issues. Please try updating the library from github.

Thank you for the answer.
Actually I see the master branch in git has new versions of files compared to mine. Cool.
Is there a specific -stable- version you recommend?

Hi there
tried getting the latest sources but got errors in compilation. It reports:

/Users/virgilio/Desktop/Freematics-master/libraries/FreematicsPlus/FreematicsMEMS.cpp: In member function 'ui
nt8_t MPU9250_ACC::readByte(uint8_t)':
/Users/virgilio/Desktop/Freematics-master/libraries/FreematicsPlus/FreematicsMEMS.cpp:16:28: error: 'i2c_ack_
type_t' was not declared in this scope


Actually file FreematicsMEMS.cpp includes (https://github.com/stanleyhuangyc/Freem ... 50a85faf35)

#include <driver/i2c.h>
#include "FreematicsMEMS.h"

but there is no driver/i2c.h neither folder nor file

Am I missing something?

Hi @virgilio / @stanley / anyoneWhoCanHelp

Just received my Freematics One+ and installed Firmware V5 onto it using Atom/PlatformIO.
Writing onto the device was SUCCESS.

I followed this link :https://freematics.com/pages/products/freematics-one-plus/guide/
upto the Atom/PlatformIO section. I believe Freematics Arduino Builder is to be used when i want to modify code. Correct me.

After that, from Serial Monitor I see this (Connects to Wifi (My phone's Hotspot) and then CLOSES the connection) immediately.

As per above discussions, I checked that I have the latest code:
https://github.com/stanleyhuangyc/Freem ... 50a85faf35

I did check with the BLE app : BleTerm, which reads HEX values as when i say read bytes :

0x46, 0x72, 0x65, 0x65, 0x6D, 0x61, 0x74, 0x69, 0x63, 0x73, 0x44, 0x65, 0x69, 0x63, 0x65

Does if mean that Freematics is actually reading things.

Any inputs on what to do at this stage ?
