Device : Telit HE910Device Firmware Version : 12.00.005Host : imx28 Communication : USB (Always connected)VBATT : 3.9 volt (Always)
I invoked cmuxt as in below linecmuxt -d -p /dev/ttyACM0 -m he910
As a result, 3 TTY ports got created ttyMUX1 , ttyMUX2, and ttyMUX3
UsagettyMUX1 : Locked for ppp connectionttyMUX2 : Application to continuously Receive Signal Strength, Network Operator Name, and few radio parametersttyMUX3 : Used for receiving GPS messages
No data is sent towards /dev/ttyMUX3. Still We could see the GPS Controller going down by itself and gets back by itself in 5 – 8 seconds at times.
In that period of time, I get 0 as response for AT command AT$GPSP?. After that 8 seconds, or so, GPS Controller is UP by itself.
Could some one help us get ourselves out of this weird problem ?
This problem occurs around 3 – 4 times in a day or so of continuous usage of Telit HE910 as explained above.
Let me know if some one needs additional information
