OTA APP to APP DFU sdk9.0.0

[martial]

HI People,

I face a problem when I do an OTA DFU from APP to APP. I compiled ble_app_hrs S110_with_dfu example fro sdk 9.0.0 and did OTA dfu. Now the device advertises in normal application mode as Nordic_HRM. What I was not able to do is an OTA DFU after that. The NRFtoolbox app hangs displaying "Connecting..". Why is that? I use

• SDK 9.0.0
• SD 8.0.0
• nrf51822 CEAAE00 (0x0079) which has 256 kB FLASH, 16kB RAM

@martial: Have you flashed the bootloader in \examples\dfu\bootloader first ?

@Hung Bei: Yes, I flashed the SD8.0, followed by the Bootloader in \examples\dfu\bootloader. By this moment, the device would advertise as DFUTarg and I am able to do OTA DFU of application hex.

@Martial: Have you update the project setting to match with your RAM size (IRAM1, IRAM2) ? Could you attache your project so I can have a look here ?

You can also try using nRF Master Control panel app and do DFU, then you can swipe right to have the log and find more information on what going on.

@Hung Bui Have attached the code above in question

@Martial: You haven't modified the project setting RAM size to match with your chip (16kB RAM). You need to update both the setting in the bootloader and the application. Please have a look here.
