Has been solved, using the S140 header file, the S340 header file is used to solve.

Thanks.

Not yet. I just tested with s140.

Can your bootloader work with s340_6.1.1? My program debugging will return 0x40 error code in sd_softdevice_enable.

Sorry, yes it is, but thisisant has modified it implemented ANT functionalities into the s340. I have rephrased my previous reply to avoid confusion.

Off-topic: What? The softdevice is not developed by Nordic?

1. You need to adjust IROM settings for the project. If you need more space for the bootloader you can allocate more by reducing the start address (IROM start, and increase the size setting with the same amount). You can see an example on how this is done in the debug variant of the bootloader project. Note that it is not possible to increase the bootloader size after initial programming without doing a full chip erase, since the bootloader start address is stored in the UICR register.

2. You can find this documentation over at thisisant's web pages, but you have to register as a user, as they are responsible of the s340 SoftDevice. But the RAM start and Flash start values, as well as how to change these can be found here in our memory adjustment tutorial.

Minimum RAM Start address: 0x20002000

Flast Start address: 0x31000
