Bootloader S332

[Woody Hung]

Hello! I am using application that support ANT+ and BLE, so i am using s332 softdevice. now I want to add BLE bootloader feature. (send .bin via BLE). but in SDK v13.0.0-1, BLE Secure DFU Bootloader support only s132 softdevice.

So, what I need: - s332 softdevice - ANT+ / BLE application - BLE bootloader

i can use it what is version of S332 softdevice.

ANT_s332_nrf52_5.0.0 or ANT_s332_nrf52_4.0.2-2?

Or another?

Hi Woody,

You should use S332 v4.0.x if you are using SDk v13.

I don't think you need to modify the bootloader to make it work with S332. It should work out of the box.

Hi Hung,

I am using S332 v5.0 and SDK 14.1's examples\dfu\bootloader_secure_ble on the DK PCA10040. it's not working, the LED 3 is on and LED 1 is not flashing. However, if I am using S132 with that bootloader, it's ok. Do you have any idea?

Hi vlau,

You may want to step into the bootloader code and check what doesn't work. Also please check log data on RTT from the bootloader.

Please ensure 'S132' has been changed to 'S332' in the preprocessor symbols and that the following:

• /components/softdevice/s132/headers/nrf52
• /components/softdevice/s132/headers

has been changed to:

• /components/softdevice/s332/headers/nrf52
• /components/softdevice/s332/headers

in the Makefile (or equivalent).
