8.1.19 Bootloader command

The bootloader command is sent to the device to put the device in bootloader mode. The key is "bootloader"
and the value is null. The device will enter bootloader mode two seconds after receiving this command. See
Section 12 on page 52 for more information about updating the device firmware.
Example:
"bootloader":null r n

8.1.20 Factory command

The factory command is sent to the device to enable factory mode. The key is "factory" and the value is null.
In factory mode, read-only settings can be written using the write setting command, the default command will
set all calibration settings to their default values, the save command will succeed when the EEPROM Cyclic
Redundancy Check (CRC) has failed, and the erase command will be enabled.
Example:
"factory":null r n
Warning - Incorrect use of this command may permanently damage the
device. Do not use this command unless instructed by customer support.

8.1.21 Erase command

The erase command is sent to the device to erase the EEPROM. The key is "erase" and the value is null.
The command acknowledgement will not be sent until the erase is complete. This will take approximately 700
milliseconds. This command can only be used after the factory command.
Example:
"erase":null r n
Warning - Incorrect use of this command may permanently damage the
device. Do not use this command unless instructed by customer support.
