4.3.35. Restore Factory Setting via At Command
function：all changeable parameter restore to factory setting, include baud rate, device
name, transmit power, user-define broadcast data, UART data latency data, verify
code ,broadcast parameter, connect parameter
Effective time：immediately，system compulsory restore
Command：
"AT:RELD"+<CR><LF>
Feedback：
"AT:OK\r\n" means command success, system restore
"AT:ERP\r\n" means invalid command, restore failed
4.3.36. Enable Module Deep Sleep
Function：enable module CPU subsystem deep sleep, (BLE subsystem isolate operation), non
deep sleep mode module can receive data via UART, under deep sleep module UART function is
disabled
Effective time：immediately
Command：
PIN32->WAKEUP：high level ->CPU subsystem enter deep sleep , module UART don‟t
receive data
PIN32->WAKEUP：low level-> CPU is not allowed to enter deep sleep, module UART able to 不允
receive data
Need to pay attention to actual level and data sending sequence, sending data must wait 50
us after set high level to low level, after sending finished, and must waiting another 50 us to set
low level to high level
