Hi,
I hope someone can assist with the following Q.
We want to use bg95 as at command modem.
We have an external microcontroller connected via uart i/f
When bg95 is set into PSM via AT command.
- what happens when BG95 RTC timeout - how will this be reflected to the ext. microcontroller?
- with UART i/f ?
or/and with an gpio output on BG95?
or else?
when BG95 module enter PSM mode , the state is similar to powndown , there are nothing to output , ( inculde UART)
in module internal , only RTC is on ,when the PSM timer is time out , the module will powerup automatically .
I attached one psm related doc for your reference .
