  1. Hi Cosmin

     

    Is it possible to access the modules i2c bus and attach devices…such as an accelerometer? Im guessing it is given the following extract from the GE863-PRO web page:

     

    The GE863-PRO³ was designed to simplify connectivity through the availability of interfaces such as SPI, IIC, SD/MMC and USB (Host/Device). Telit offers a vast collection of reference designs enabling use of the PRO³ with external peripherals such as camera, keyboard, display, Wi-Fi®, Bluetooth®, SmartCard, SD Card

     

    Any idea where the reference designs are located? I have the reference design for adding a GPS module….was wondering about the others?

     

    Thanks

    1. Hi Bruce,

       

      There are some documents like  Low Level Driver APIs Application Note, Bluetooth Library User Guide, Short Range Libraries User Guide, GE863-PRO3 GPS Package User Guide, GE863-PRO 3  Linux CAN Package Software User Guide.

       

      Please use your direct contact at distributor or Telit for reference designs.

       

       

  2. I2C failing with “Operation not allowed”

    Hi

    I have a problem with the I2C commands on a TELIT GE910-GNSS. Any read command fails. For example:

    AT+CMEE=2
    OK
    AT#I2CRD=9,8,31,28,1
    +CME ERROR: operation not allowed

    This is on a vanille GE910-GNSS module with new firmware.

    AT+CGMR
    13.00.107

    Please assist
