nRF5_SDK_15.3 ble_app_hrs_c connect to a periphera fatal error

[ShunYi]

Hello , I come from taiwan.

I am using ble_app_hrs_c to connect my heart rate watch

I can set m_target_periph_name to search for devices with the same name and connect ,

But I want to connect to a peripheral with a given address got fatal error

SDK : 15.3

See nRF Connect ,my heart rate watch MAC = E7:9C:C0:51:62:51

if is_connect_per_addr = false can connect my heart rate watch but I want to specify mac connection

What should I do T_T

Are you sure the mac address of the smart watch is of the type Random Static? If it uses e.g. a Private Resolvable address, that approach won't work.

Read more about the different address types here.

Best regards,

Hello Simon , I don't know type but I tried all type still can't solve my problem

[Simon]

I guess the address is private resolvable. Then you would need the IRK in order to resolve the address, which you can get by bonding with the device. Read more here. What smart watch do you have?

Best regards,

I am trying to intercept BLE packets

But I don't know how to parse

[Simon]

Take a look at the library <..>/components/ble/nrf_ble_scan/nrf_ble_scan.c which contains many functions for parsing/decoding the advertising packet.

Best regards,

Simon
