Combined BT and serial Bootloader for S132

[Uwe]

The existing Development Environment:
- nRF52832
- SDK 11
- Softdevic S132
- Eclipse

Project Status:
- Nearly finished with working OTA - bootloader

Existing Bootloader:
- Based on SDK11: ../examples/dfu/bootloader/pca10040/dual-bank_ble

Goal:
- Combined serial and OTA - bootloder

Questions:
1. Does there exists a solution for a combined bootloader?
2. Is it in principle possible to integrate a combined boot booader into the limited Boot Flash area?
3. Which existing serial bootloaders from which SDK are recommented for finding a fast and save solution.

Hi Frank, 

 

1. We don't have an example doing that. There was some discussion about it here. 

2. Yes, it's possible. I don't see any problem to combine 2 transportation layers. We had customers managed to do that. You can always expand the 

3. We suggest to move to the latest SDK which is v15. From SDK v12 we completely refactorized the bootloader (secure bootloader) and it's much easier to make multi transport layers in one bootloader (just include the 2 transport library files in)  . We recommend you to switch to SDK v15 for developing new application.
