Hey, do you have an idea why my sensor (Sierra Wireless Location Sensor) is detected properly but sending absolutely no data when accessed via your example?
Cheers,
Philipp

Hey , Using the same code to read data from the "u-bolx 7 GPS/GNSS Location Sensor " . But everytime I am getting the sensor state as initialising. So is it the problem with sensor initialisation ? If yes how to initialise this sensor ?
