XIAO BLE SENSE cannot communicate with IMU sensor

[Hardeep_Singh]

Thanks for your response. I tried using “Seeed nRF52 mbed-enabled Boards 2.8.1” but get this error:

Error: 13 INTERNAL: Cannot install platform: installing platform Seeeduino:[email protected]: searching package root dir: no unique root dir in archive, found ‘/Users/a2530/Library/Arduino15/tmp/package-3768760097/.github’ and ‘/Users/a2530/Library/Arduino15/tmp/package-3768760097/bootloaders’

I was able to specifically install the “Seeed nRF52 mbed-enabled Boards” version 2.7.2, but I get the same error as Hardeep_Singh when I try to update it to 2.8.1 - it’s clear that something is broken in the Board JSON file provided by Seeed. I hope Seeed can see and fix this! @msfujino - the 2.8.1 version doesn’t install on the Arduino IDE (I use version 2.0.3, which is the current download).

I installed on IDE 1.8.19 and am using it with IDE 2.0.3.
For problems with IDE2.0, you can post in the following forum, which will confirm and solve your problem in a very short time.When using mbed2.8.1, please also refer to the following link.

XIAO_BLE_Sense(mbed 2.7.2) battery charge and voltage monitor, analogRead(P0_31) does not work

XIAO_BLE_Sense has battery charging and battery voltage monitoring functions. I am trying to check these functions with “mbed 2.7.2”. The charging function worked as expected, but “analogRead(P0_31)” to read the battery voltage did not work. To check, I tried other analog pins from A0 to A5, and “analogRead()” worked without any problem. [XIAO_BLE_BatteryCharge] After much analysis, it seems that there is a problem in the macro “analogPinToPinName(P)” used in the “analogRead()” function. In …

Are you suggesting using IDE 1.8 to make BLE sensor work until Arduino fixes 2.0.3 issues?

[msfujino]

If you install mbed2.8.1 using the board manager of IDE1.8.19, it will be installed in the following directory This can also be used from IDE2.0.3.

\Arduino15\packages\Seeeduino\hardware\mbed\2.8.1

Hi everyone,
I am working with xiao ble in mbed version. I could not make the lsm6ds3 and mlx90614 work together(at same time). But it was possible for me to work the lsm6ds3 with max30100 and get the imu values and spo2. When i work with mlx90614, it is not printing any imu values or temperature and also it did not pop any error when i compile.

Hi,
sounds like an address issue? if you ask me?

Hello Dave,

I followed your exact steps to try to get the HighLevelExample sketch to communicate with the IMU however, I still get a device error and static values for the accelerometer and gyroscope. I’m using a Linux machine and have Arduino 1.8.19 installed. I have the same versions of the libraries installed that you have.

Thanks in advance for you help,
Daniel

Seeed nRF52 mbed-enabled boards 2.8.1 IMU return static values

Hi, I i’m trying to use the IMU the Seeed XIAO sense with the Seeed nRF52 mbed-enabled boards 2.8.1. I am using the HighLevel exampel, however it only returns a static value for accelerometer, gyroscope and the thermometer. Serial output: Y1 = 0.7291 Z1 = 0.7291 Gyroscope: X1 = 104.5800 Y1 = 104.5800 Z1 = 104.5800 Thermometer: Degrees C1 = inf Degrees F1 = inf There is no error during upload or setup. Hope you can help recieving real readings.
