Freematics Forum

First of all, the forum wont allow me to post on Freematics Hardware, as it kept logged me out whenever i wanted to post.

I have purchased Freematics ONE+H and load it with telelogger.ino via IDE.
1. I tried to use GNSS_STANDALONE, however when i check the buffer buf, this is the following string:

$GNIFO,000000,00000000,0,0,0,0,0,0,9999*C7
�P'�?�0�? @?�����*?�0�? ��
�p'�?���?

2. I tried to use GNSS_CELLULAR and check the buffer after sending atcommands to SIM7070, and it returns the following result when i check the m_buffer received:

+CGNSINF: 0,,,,,,,,,,,,,,,,,

Please help why all the gps module are not working properly.

Note that i have supplied the module to 12V with my variable power supply.

I'm going with the exact same issue. There is an endless cycle of "Searching" and "Activating" on the Freematics ONE+ (Model B). I either use Freematics Builder (firmware v5\teleloger) or leave the APN field empty in the configuration.h or Builder: is inoperable.

Are you using the latest code? Please provide your serial output.

It sounds like you're encountering issues with both the GPS and cellular modules on your Freematics ONE+H device. The GPS data string you provided looks corrupted.fireboy and watergirl This could be due to several reasons:
Baud Rate Mismatch: Ensure that the baud rate settings for the GNSS module match those in your code. The typical baud rate for GNSS modules is 9600 or 115200.
Antenna Connection: Ensure that the GPS antenna is properly connected and positioned to receive signals.
Firmware and Initialization: Make sure the GPS module's firmware is up to date and that it is properly initialized in your code.
