COMMAND DESCRIPTIONS
Read Flash
This command is used to read the encrypted image of
the flash that resides on the radio module. If the image
has already been decrypted, then this command will
report an error.
*The length of this command is dictated by the dynamic
memory heap. If the heap is mostly free, then a length of
up to 700 bytes could be accepted. However, if the heap
is full, the command will return with an error, or possibly
no response at all if the heap is completely full.
PROCESS TO MANUALLY UPGRADE LT2510
Using the above AT commands it is possible to upgrade a LT2510 over the UART from a microcontroller or other
device. The basic steps to do this are:
1. Make sure the OEM Host has a copy of an encrypted binary firmware upgrade file.
2. Erase the Existing flash on the LT2510
3. Write binary image to flash
4. Decrypt FW image
5. Reset radio to begin using new FW image
a. Command: 0xCC 0xC6
b. Response: 0xCC 0xC6
a. While not end of binary file
b. Check EEPROM Write
c. Verify Read response is the same data that was written
d. Increment start position
e. Verify length
f. Repeat steps a-f until entire image has been loaded
a. Command: 0xCC 0xC5
