not getting any data

[ghost]

hello
i just want to display the batteries information using just gps port (tx rx) without connecting it to inverter, the data im getting are always like the standalone test without any change. can you help me with it asap
thank you in advance

[ArminJo]

No problem. What have you tested so far?

[ghost]

I've just connected the gps pins(tx rx Gnd)as per your circuit and I want to display the data on the screen as shown in this picture(i have only 5 batteries)

i didn't modify the code i just upload it on Arduino Uno, I'm getting the standalone values on the screen not the real time data from the bms
I dont want to connect it to an inverter i just want to display all the data related to the batteries and the bms.
my connections:



please can you help me if the code must be modified or something is wrong with the connection. I want the real time data(voltage, temperature, current ...)
thank you in advance

What is the Serial output of the program?
is line 155 commented out //#define STANDALONE_TEST

this picture is live data from bms application connected to the phone using bluetooth i want the same data on lcd or serial
in addition i have 5 ncm (53AH 3.7v each) batteries

[ArminJo]

And I want you to check, if line 155 is commented out //#define STANDALONE_TEST.

[ghost]

yes it is commented

i extracted the file and uploaded the code again it gave me this on the serial
