I'm glad that it works now :)

Well, It's working now. I adapted the same steps from the example to my application and get it to work. I've made some changes in bootloader to satisfy my application requirements (had to enable twi) and could discover that it wasn't working because of some twi miss-operations. When I removed uart I end up changing some required delay times which caused some crashes. Anyway, your assistant was very important. Thanks. Your dfu guide is awesome!

Thank you (again) for your support!

Att, Luccas

Hi, I just tried to load the bootloader_secure example (release) and created an package from ble_app_hrs example, using a new generated key pair. It worked this way! Now I'm trying to discover why I couldn't do it with my app, maybe because nrfutil wasn't up to date. Thanks for the quick reply. Your guide is very useful! If I can't get it to work I'll get in touch. =)

Have you made sure you use the same private.key file to generate the public_key.c and the DFU .zip package ?

You may want to send me the .zip file, the private key you generate, the publickey.c, the bootloader hex, the application hex file (any hex file maybe from one of our example) so I can check here.

So I tried to update sdk to last one (13.0.0) together with S132 v4.0.2, and followed this guide devzone.nordicsemi.com/.../

I could generate my init package and connect to dfuTarg that uses my own dfu_pub_key. But now I got another error: REMOTE DFU INVALID CRC ERROR. I used the same function form guide for generating .zip package. Any tips?

Thank you very much for your attention!

Hi, I'm using SDK 12.1, yes I tried to disabled LOG and UART. After doing this I 'm still able to connect to DfuTarg, but when I send the package I get the TIMEOUT. I'll try more tests using stock example, I tried once without success also.

Hi Luccas,

Which SDK are you using ?

Have you tried to disable LOG ? NRF_LOG_ENABLED = 0 ? When exactly do you get GATT CONN TIMEOUT ?

Do you have same problem when you test with the stock (release) example ?
