how to dfu on S332_ble_ant_app_hrm

[kenyon]

application : sdk17.1/multiprotocol\ble_ant_app_hrm\pca10040\s332

i want to realize ble dfu on this demo, but i can not find the relevant example. how should i do?

Hi,

You can refer to the bootloader exmaples in the folder you have found. Ther eis no exmaple with S332 specifically, but the sampel under pca10040_s212_ant shows how you can do DFU over ANT (the sample is qually valid for S332). Similarily, the example in pca10040_s132_ble demonsrate doing DFU over BLE if that is the transport you are interested in. The method is the same regardless of which exact SoftDevice variant is being used.

Hi
Can I directly perform the BLE DFU using this routine“pca10040_s132_ble”? Or do I need to modify some parameters?

Hi,

pca10040_s132_ble is an example that demonstrate DFU over BLE. You can use this bootloader with your application as well, but need to make sure you change the S132 define in the project with S332. Also, you mus replace the include path to point to the S332 headers instead of the S132 headers.

Lastly, you must make sure your application end address is low enough to make room for the bootloader (and any persistant storage need to be in between). See the Memory layout in the bootloder documentation for details. You can also refer to the bootloader example documentation.

Hi
i try to replace path to point to the s332 headers instead of the s132 header,
but there is no files in s332.
how should i do ?

Hi,

The S332 SoftDevice including header files is only available from Garmin (See S332 ANT), so you must use what you have obtained from them.

However, let me ask if it was a typo when you wrote S332 in the initial post? If you do not use ANT, then S332 is not appropriate, and you should use S132. In that case, the bootloader sample can be used as is (though you neeed to replace the public key as explained in the BLE Secure DFU Bootloader documentation).

Hi
Oh, I'd like to clarify something. I want to use S332's ANT+BLE in application, and I also want to perform DFU upgrade via Nordic BLE.

I see. Then you need to use the S332 header files that you get from Garmin (it is part of the S332 distribution).
