5.2.10 Read Data from FLASH on Module

Function: read data from FLASH on module. This FLASH size is 512KB. The FLASH is

264 bytes per block and 2048 blocks totally. The operations are with in a BLOCK. If you need

read data in 2 blocks, then you must send read command twice.

Host sends:

Frame 0x05 BlockNo Address Bytes Checksum

BlockNo: 2 bytes, the reading block number: 0x0000 ~ 0x07FF, MSB first.

Address: 2 bytes, the address in block: 0x0000 ~ 0x0107, MSB first.

Bytes: 2 bytes, the number of bytes to be read: 0x0001 ~ 0x0108, MSB first.

Success:

Frame 0x05 Data Checksum

Data: the data read result.

Failure:

Frame 0xFA Checksum

Example:

Send: 0x00 0A 00 05 00 02 00 10 00 08 15

Return: 0x00 0C 01 05 00 01 02 03 04 05 06 07 08

5.2.11 Write Data into FLASH on Module

Function: write data into the FLASH on Module. This FLASH size is 512KB. The FLASH

is 264 bytes per block and 2048 blocks totally. The operations are with in a BLOCK. If you need

to write data in 2 blocks, you must send write command twice.

Host sends:

Frame 0x06 BlockNo Address Bytes Data Checksum

BlockNo: 2 bytes, the writing block number: 0x0000 ~ 0x07FF, MSB first.

Address: 2 bytes, the address in block: 0x0000 ~ 0x0107, MSB first.

Bytes: 2 bytes, the number of bytes to be write: 0x0001 ~ 0x0108, MSB first.

Data: the data to be written.

Success:

Frame 0x06 Checksum

Failure:

Frame 0xF9 Checksum

Example:

Send: 0x00 12 00 06 00 02 00 10 00 08 00 01 02 03 04 05 06 07 0E

Return: 0x00 04 01 06 03

5.2.12 Set UART Communication Baud Rate

Function: set UART communication baud rate of the module. After module received the

command, it will first save the new setting, and then send the executive result according to the
