Hi Christian The system is working now, thanks for the support, however, the bluetooth led is not blinking on the Arduino rev2 , is it normal ? Best regards Philippe Hi Philippe, I had to do some investigation on this, it is correct that the RGB-LED is not used in bluetooth mode. This is controlled...

Hi Philippe, Arduino updated the BLE library so it is currently too big. I need to optimize the code but for now please use the older version. See troubleshooting section below for details.

6. If you get an error with code size on Arduino Uno WiFi, use ArduinoBLE library v.1.2.2.

Thanks Christian...
seems to be a too hard job for now... unless someone has ever done it ...

You are right. To make it as simple as possible for you we ended up using the Arduino Uno WiFi with bluetooth module integrated.

I use a laptop power supply with about 19V connected to the shield.

Hi Paul, using a voltage higher than 16.5V may reduce the lifetime of the Bosch LSU 4.9 sensor.

Hi to all
Do I strictly need a wifi arduino board, I have a BLE arduino module to connect bluetooth apps,
kind regards

Hello Philippe,

No, but you would need to write a custom version of the Lambda Shield 2 smartphone code.

Hi I have a problem with lambda shield 2 with original Bosch sensor. The system was working fine but suddenly stops reporting. When I check the serial monitor I receive error code 0x287F (no sensor connected) is there any way to troubleshoot it or is it possible that the sensor is dead? Hi Paul, Ba...

Hello, Currently the new knock setting are lost when we power cycle. How can we save the settings to memory? How are you changing the knock setting? //Define registers and parameters used. #define SPU_SET_PRESCALAR_6MHz 0b01000100 /* 6MHz prescalar with SDO active */ #define SPU_SET_CHANNEL_1 0b1110...

Hello Sebastien, The maximum temperatures can be found in the sensor data sheet . Exhaust gas temperature < 930°C range (operating) Exhaust gas temperature < 1,030°C range (max.) for short time Hexagon temperature < 600°C Wire and protective sleeve < 250°C temperature Connector temperature < 140°C H...

The sensor heats up and all seems happy, but i have no display at all. Hi Dave, I hope you are well! Let's see if we can solve your problem. First, all of the correct files for your shield is available on the Lambda Shield product webpage . I quickly loaded the default ADAFRUIT TEST file into the U...
