M16 SHT31 sensor disconnected

[bsarra]

I've identified an issue with my M16 board whereby the SH31 sensor becomes disconnected after the setup() function and can no longer be read.  I've tried a number of variations on the bus settings, but there seems to be no effect.  The relevant setup() code is this:

PHP Code:

    Wire.begin(4, 5);
//    Wire.setClock(100000);
    Wire.setClock(10000);
    Wire.setTimeOut(1000);
    sht.begin();
    sht.read();
    temperature = sht.getFahrenheit();
    humidity = sht.getHumidity();
    int error = sht.getError();
    if (error != 0) {
        uint16_t stat = sht.readStatus();
        ESP_LOGW("kincony", "Temperature sensor Error status: 0x%04x, read status: 0x%04x",
                error, stat);
        logSHT31BitStatus(stat);
    } 


This works, however, once inside the loop(), attempts to read the SHT31 fail as disconnected and cannot be reset, even using the HARD option.

PHP Code:

        if (sht.isConnected()) {
            sht.read();
            temperature = sht.getFahrenheit();
            humidity = sht.getHumidity();

            int error = sht.getError();
            if (error != 0) {
                uint16_t stat = sht.readStatus();
                ESP_LOGW("kincony", "Temperature sensor Error status: 0x%04x, read status: 0x%04x",
                        error, stat);
                logSHT31BitStatus(stat);
            }
        } else {
            int error = sht.getError();
            ESP_LOGE("kincony", "Temperature sensor connection failure, HARD resetting...");
            ESP_LOGW("kincony", "Temperature sensor Error status: 0x%04x", error);
            sht.reset(true);
        } 


Could this be a conflict with the U8G2?
