ZMOD4410 Sample Code - check error event return value

Question

Hi there 
 I'm reading through the sample code for the ZMOD4410 2nd Gen, ULP and PBAQ. There is a function called after the read measurement call e.g. zmod4xxx_check_error_event(sensor); 
 One of the return values that is checked in the switch is ZMOD4XXX_OK - this gives and error. Is this correct? It seems as though this is wrong. Can someone confirm this is correct?? 
 /* Check if measurement is running. */ if (zmod4xxx_status & STATUS_SEQUENCER_RUNNING_MASK) { /* Check if reset during measurement occured. For more information, * read the Programming Manual, section "Error Codes". */ ret = zmod4xxx_check_error_event(sensor); switch (ret) { case ERROR_POR_EVENT: HAL_HandleError(ret, "Reading result: Unexpected sensor reset!"); break; case ZMOD4XXX_OK: HAL_HandleError(ret, "Reading result: Wrong sensor setup!"); break; default: HAL_HandleError(ret, "Reading result: Unknown error!"); break; } } 
 Thank you!

Hello Sean, 
 After doublechecking this with our sensor team. Let me correct my previous answer. 
 After reading the status then it check if the measurement is still running. 
 
 In case the measurement is still running it enters the if condition and goes inside the switch case you are referring to. 
 Normally, after the proper delay it shouldn't enter this if condition. 
 Entering this if condition means that the measurement is still running while it shouldn't. Therefore the timing is not correctly implemented if this if condition is entered. Although the sensor reports OK, the measurement setting is not okay. 
 
 Hope this makes things clear for you.
