Useful Mynewt/Nimble Structs and Fields

Some useful Mynewt or nimble fields to display can be seen below:

ble_phy_stats - PHY stats for traffic tracking

ble_ll_stats - Link layer stats

ble_ll_conn_stats - Connection stats

g_ble_ll_adv_sm - Advertising state machine

g_ble_ll_stack - Link layer stack

For example:

(gdb) monitor halt

(gdb) set print pretty on

(gdb) p ble_phy_stats

$16 = {

s_hdr = {

s_name = 0x0,

s_size = 0 '\000',

s_cnt = 0 '\000',

s_pad1 = 0,

s_next = {

stqe_next = 0x0

}

sphy_isrs = 0,

stx_good = 1,

stx_fail = 0,

stx_late = 0,

stx_bytes = 27,

srx_starts = 0,

srx_aborts = 0,

srx_valid = 0,

srx_crc_err = 0,

srx_late = 0,

sno_bufs = 0,

sradio_state_errs = 0,

srx_hw_err = 0,

stx_hw_err = 0

}

Memory Manipulation

You can display the memory contents of a specific address via the x command.

To see the main stack pointer location on an ARM chip, for example, run:

(gdb) x 0

0x0: 0x20008000

You can also adjust the output size with the optional x/nfu flags:
