Hi,

shouldn't this
#define CHECK_RESULT(a,b) do{if(a=b)

rather be
#define CHECK_RESULT(a,b) do{if(a!=b)

in Seeed_SHT35.h line 64

Even though a 1.0.1 and 1.0.2 has been tagged in the repository. Only version 1.0.0 of the library is available from the Arduino Library Manager. This causes users to use an outdated version of the library that is missing the critical fix from #5

Explanation

The cause is shown here in the library's dedicated indexer logs web page:

2023/04/03 14:12:03 Checking out tag: v1.0.1
2023/04/03 14:12:03 Release Grove - I2C High Accuracy Temp_Humi Sensor SHT35:1.0.0 already loaded, skipping
2023/04/03 14:12:03 Checking out tag: v1.0.2
2023/04/03 14:12:04 Release Grove - I2C High Accuracy Temp_Humi Sensor SHT35:1.0.0 already loaded, skipping

Unfortunately, the logs don't communicate about this particular thing very clearly, but what this tells us is that the version value in the library.properties metadata file was not updated before creating the v1.0.1 and v1.0.2 tags (note that the indexer checked out tag v1.0.2 , only to find the release version was 1.0.0).

You can see it here:

https://github.com/Seeed-Studio/Seeed_SHT35/blob/v1.0.2/library.properties#L2

version=1.0.0

Even though Git tags are the unit of release for the Arduino Library Manager, all versioning is done according to the version field of the library.properties file.

For this reason, the indexer will reject any tag that has the same value in its version field as a release already in the index.

Solution

The solution is to make another release of the library:

1. Update the version value in library.properties to the version that will be used for the new release.
2. Create a new release or tag in the library repository.

The indexer system will pick up that new release and it will be available from Library Manager within a day.

The non-compliant release will still be missing, but since the newer release will be available, that is no problem.

The fact that the metadata update was forgotten two releases in a row indicates this problem is likely to occur again. I suggest producing a formal library release procedure document for use by the Seeed Studio developers when making releases of Seeed Studio's many valued Arduino libraries.

When using
#define HIGH_REP_WITH_STRCH 0x2C06
and example sketch it inits ok but can't read. Sometimes it will work until I power cycle.
Changing to any of the 0x2400 no stretch settings works.
Oscilloscope shows no clocking or data after SCL held low and release with 0x2C06.
0x2C0D and 0x2C10 work for some reason. 0x24XX always works.

The latest version v1.0.2 has a critical bug fix in it. Can we get this version on PlatformIO? https://platformio.org/lib/show/5873/Grove%20-%20I2C%20High%20Accuracy%20Temp_Humi%20Sensor%20SHT35

Hi,

I am trying to get the heater status, enable/disable if needed.

        bool heaterstatus = sensor.heaterStatus();

exit status 1
no matching function for call to 'SHT35::heaterStatus()'

How can i get and then enable/disable the heater using this library?

In the Arduino BSP for nRF52 – which Xiao BLE uses – err_t is defined as uint32_t, whereas in this library it is defined as:

typedef enum {
  NO_ERROR = 0,
  ERROR_PARAM = -1,
  ERROR_COMM = -2,
  ERROR_OTHERS = -128,
} err_t;

As a quickie, I changed the name of the enum, and all references to it, to err_tp. The example now compiles on Xiao BLE. I also had to add a #define for the I2C pins:

#define SDAPIN PIN_WIRE_SDA
#define SCLPIN PIN_WIRE_SCL
