Dear Nordic Support Team:
software: nRF5_SDK_15.2.0_9412b96
hardware: nRF 52832 DK, Senirion SHT30-DIS-B
error: TWI communication error at sending measurement command of the sensor SHT30
According to the measurement commands of the sensor SHT30, the nRF 52832 DK as the TWI master, writes 0x212D and 0xE000 into the sesnor SHT30. In the wave shapes from the oscillograph,the command 0xE0000 is right, the command 0x212D is wrong, and only error at the 2nd byte 0x2D.
ralated program code:
uint8_t reg[] = {0x21,0x2D};
err_code = nrf_drv_twi_tx(&m_twi_0, 0x44, reg, sizeof(reg), true);
uint8_t reg[] = {0xE0,0x00};
err_code = nrf_drv_twi_tx(&m_twi_0, 0x44, reg, sizeof(reg), true);
However, I used the othe TWI tool to test the sensor with same commands, the measurement results were right.
To compare the wave shapes, I found out that the interval of error communicaiton by the nRF52832 DK controls is wider than other TWI tool. maybe that is the matter.
Could you tell me how to decrease the interval by nRF SDK function?
Thanks.
