I2C bus error after sending standby cmd to GPS
I'm trying to put the GPS in standby mode using the PMTK command specified in the documentations, but everytime the command is executed: I get an I2C bus error, which I don't understand why.
- hw_version 3
- fw_version 8
- product_id 61459
- firmware: v0.0.8
Is this a bug? Anybody else who experienced the same problem?
def gpsStandby(self): print('Sending standby cmd to gps...') standby = "$PMTK161,0*28\r\n" self.i2c.writeto(GPS_I2CADDR, standby) time.sleep(0.2)
Once the GPS module goes into standby the i2c stops working, you can no longer wake it up via i2c, all you can do is a reset via the pytracks deep sleep function.
