Data received from the UM7 sensor is not of the format that is specified in datasheet , so we are facing the problem of not receiving data with the UM7 code .

According to specification , starting bytes for each packet should be 's' , 'n' , 'p' but every time the packet starts with different data bytes if we see the transmit pin of UM7 directly in CRO

The current code used is found in the link below
