Instruction format: #807# user password #X##
For example: #807#0000#30##
Description: After receiving the instruction and confirming that user password is correct, TLT-2H will set
historical rewire sampling frequency as X. If X=0, the device will close historical data rewire. If X!=0, the device
will take X seconds as interval to store received GPS data. After success, it will return confirmation message to the
sender: SET SAMPLING OK.
Note: 1. X is historical rewire sampling frequency, whose defined domain is [0, 999] with second as unit.
2. Size of each data quantity is around 100B (BYTE).
3. Memory space distributed to historical data rewire is 864KB (BYTE) and stack override method is used to
update data storage. If X=30, data for about 3 days will be rewired. If X=300, data for about 30 days will be
rewired. When stored data reach 864KB, newly received data will override earlier data.
4. If power saving function is activated and TLT-2H remains static for a long time, historical rewire will be
automatically closed until TLT-2H is wakened up and GPS is turned on.
