Debug

The following debug commands are available on Bluefruit LE modules:

AT+DBGMEMRD

Displays the raw memory contents at the specified address.

Codebase Revision: 0.3.0

Parameters: The following comma-separated parameters can be used with this command:

The starting address to read memory from (in hexadecimal form, with or without the leading '0x')

The word size (can be 1, 2, 4 or 8)

The number of words to read

Output: The raw memory contents in hexadecimal format using the specified length and word size (see examples

below for details)

# Read 12 1-byte values starting at 0x10000009

AT+DBGMEMRD=0x10000009,1,12

FF FF FF FF FF FF FF 00 04 00 00 00

# Try to read 2 4-byte values starting at 0x10000000

AT+DBGMEMRD=0x10000000,4,2

55AA55AA 55AA55AA

# Try to read 2 4-byte values starting at 0x10000009

# This will fail because the Cortex M0 can't perform misaligned

# reads, and any non 8-bit values must start on an even address

AT+DBGMEMRD=0x10000009,4,2

MISALIGNED ACCESS

ERROR

AT+DBGNVMRD

Displays the raw contents of the config data section of non-volatile memory

Codebase Revision: 0.3.0

Properties: None

Output: The raw config data from non-volatile memory

Use these commands with care since they can easily lead to a HardFault error on the ARM core, which will

cause the device to stop responding.
