App freezes

Post by wiebel » 29 May 2023 18:55

Hi,

I bought the lambda starter kit with Arduino Wifi so i can use the app.
But the problems start with the app, sometimes it says no signal, but when I do have a signal, tha app freezes a lot.

Hello Wiebel,

Lets figure out what the problem is.

1. Have you updated the Nina firmware on the Arduino Uno Wifi? See the troubleshooting section.
2. What phone and OS version are you using?

Thank you.

1. I think I did but i am not sure, its my first time with a arduino so when i get home i need to check again.

2. I got a realme 7 pro with Android 12.
A think to keep in my mind that i downloaded a apk of the app because the play store Blocked me from download it.

I have reset the Adruino and updated it again, and uploaded the code again.
When I connected the arduino I had a signal almost directly and it look liked it didnt froze but I need to drive my bike to say for sure.
But I think the problem is solved.

I am investigating the google play store issue where the app cannot be installed for some users. I have tested it using Android 12 and 13 without seeing this problem so there is no compatibility issue for the Android versions.

I drove my bike a little more and the app works great now, but when i give a gas to about 1/3 of the thottle it saids that it has 11.02 AFR like its stuck but when i give more than 1/3 throttle it goes to around 13.5 and moves a little around like it should.
And when i idle its also around 14 but when i give it a little gas straight to 11.02 AFR.
