Yeah, I have looked at pag 46 of the datasheet and I think I respect what they ask, but still not working. Could you let me see your bme68x_i2c_write and bme68x_i2c_read functions, please? I do not know how to make them in a different way ... View more

Hi, I've got the same problme. Please, could you share the commn.c file where you have written the read write i2c functions? I'm sorry to ask, but I cannot resolve the problem. Thanks ... View more

Hi, after lots of trouble I'm making progress. Now, the problem is about the getting new data. Indeed, the output is this: I2C InterfaceAPI name [bme68x_interface_init]: Tutto ok API name [bme68x_init]: Tutto ok API name [bme68x_set_conf]: Tutto ok API name [bme68x_set_heatr_conf]: Tutto ok Sample, TimeStamp(ms), Temperature(deg C), Pressure(Pa), Humidity(%), Gas resistance(ohm), Status API name [bme68x_set_op_mode]: Tutto ok API name [bme68x_get_data] Warning [2] : No new data found API name [bme68x_set_op_mode]: Tutto ok API name [bme68x_get_data] Warning [2] : No new data found From another issue of Bosch community, I understood that the problem is probably related to the I2C write and read functions I have implemented in the common.c file.  I have implemented the functions in this way, is it correct? BME68X_INTF_RET_TYPE bme68x_i2c_read(uint8_t reg_addr, uint8_t *reg_data, uint32_t len, void *intf_ptr) { uint8_t dev_addr = *(uint8_t*)intf_ptr; ret_code_t ret_code; ret_code = nrf_drv_twi_tx(&i2c_instance, dev_addr, &reg_addr,1,false); if(ret_code != NRF_SUCCESS) { return ret_code; } ret_code = nrf_drv_twi_rx(&i2c_instance,dev_addr, reg_data, len); if (ret_code == NRF_SUCCESS) return BME68X_OK; else return 1; } BME68X_INTF_RET_TYPE bme68x_i2c_write(uint8_t reg_addr, const uint8_t *reg_data, uint32_t len, void *intf_ptr) { uint8_t dev_addr = *(uint8_t*)intf_ptr; ret_code_t ret_code; uint8_t send_tmp[10] = {0}; send_tmp[0] = reg_addr; memcpy(send_tmp+1, reg_data, len); ret_code = nrf_drv_twi_tx(&i2c_instance, dev_addr, send_tmp, len , false); if (ret_code == NRF_SUCCESS) return BME68X_OK; else return 1; } If the logic of the function is not correct, please could you tell me how I have to make it (the logic of the functions I mean)?

Hi again, after some troubles, I finally get the correct chip ID value. But now I have a different kind of problem. The first time I connect to power the sensor and run the program, I have this result: I2C InterfaceAPI name [bme68x_interface_init]: Tutto ok API name [bme68x_init]: Tutto ok API name [bme68x_set_conf]: Tutto ok API name [bme68x_set_heatr_conf]: Tutto ok API name [bme68x_set_op_mode]: Tutto ok API name [bme68x_get_data] Warning [2] : No new data found I have waited some times but it seems to be blocked in somewhere I do not know. If I push the reset button of microcontroller, I obtain a different result: INIZIO BME I2C InterfaceAPI name [bme68x_interface_init]: Tutto ok API name [bme68x_init]: Tutto ok Here, I see that the microcontroller is stopped in the bme68x_set_conf, and in particular it cannot exit the do while cicle at line 444 of bme68x.c file (it seems that the code want to put in sleep mode the sensor but it is not able). Do you have any idea of why I get these problems? I have not modified the bme68x.c file. ... View more

Hi Ayashkant123, I'm using BME688 sensor with nRF52832 dev kit, too. I'm having some troubles using the APIs given by bosch https://github.com/BoschSensortec/BME68x-Sensor-API. To make them work, I have to adapt the common.c file to nRF52832 standard, but I'm not sure if I make it all right. You should have done it, should you? Would you like to share the common.c file, please? I would be very thankfull ... View more
