Thanks for your response.
Actually we don’t have any prooblem in watchdog handling. In order to reduce power consumption in Q2686 module we are using AT command “AT+W32K=1,0”, by executing this command we are able to observe the module entering to slow idle mode. Similarly by executing AT command “AT+W32K=0,0” we are able to observe the module switching back to wake-up state in our sample test code.
While using the same approach in our regular product code, we are getting module re-start sometimes after completion of data upload via GPRS. We have tried various timing combination for sleep and wake-up sequence but in all the combinations the module is getting re-start sometimes. The re-start behavior is random in nature and the max code execution without re-start has been observed is one hour. So I would like to know is there any sequence or any specific timing to be followed during the Sleep and Wake-up routine/sequence.
Is there any sample code or application notes is avilable to know the usage of low power consumption in Q2686.
Note: In AT command guide, it has been mentioned that when above said command (AT+ W32K = 1,0) is enabled the power down is active after 1 to 15 seconds.
Please let me know your feedback, if any
