We are using a BG96. RESET_N and PWRKEY are connected to GPIOs. We want to persistent disable the BG96 (flight mode) which should persist over an power on reset. Can we simply hold RESET_N at low level to keep the module out of operation. Or is there an other recommended solution. Is it necessary to switch off VBAT_BB or VBAT_RF?
1 .hold RESET_N at low level is not recommended ，Because the power on and reboot are managed by PMIC, PMIC is essentially a MCU, which is required by time sequence.
- if you need power down the module , pls
3, if you need to power up the module
it can be turned on by driving the PWRKEY pin to a low level for at least
4 if you need to power on and power down the module regularly， PSM is another choice
for the detail ，pls refer the below docs
Is it allowed to switch off VBAT_RF to disble sending any signals over the air, like flight mode?
