  • Page 41: Power Off

    ME310G1 Hardware Design Guide In some use cases ON_OFF* can be tied fix LOW taking in account two limitations: 1. PSM wake-up asynchronous capability will be lost. 2. To perform an unconditional shutdown it is necessary to send AT#SYSHALT command and then cut Vbatt. Power Off The proper procedure to power-off the module is to use the AT#SHDN command.

  • Page 42: Unconditional Shutdown

    ME310G1 Hardware Design Guide Unconditional shutdown The following flow chart shows the proper procedure for unconditional shutdown of ME310G1 except in PSM mode. When the procedure is completed the ME310G1 is reset and it stops any operation. After the release of the line, the ME310G1 is unconditionally shut down, without performing any detach operation from the network in which it is registered.

  • Page 43: Wake Up From Deep Sleep Mode

    ME310G1 Hardware Design Guide Warning: Unconditional Hardware SHUTDOWN by toggling VBATT Power, must not be used during the normal shutdown operation of the device since it does not detach the device from the network and can damage the memory content. It shall be kept as an emergency exit procedure.
