I'm trying to determine DFU_APP_DATA_RESERVED and FDS_VIRTUAL_PAGES. According to this Q&A, DFU_APP_DATA_RESERVED must be the same FDS_VIRTUAL_PAGES, if FDS_VIRTUAL_PAGE_SIZE is 1024.
My application uses 11 pages, so 11+the size peer manager uses must be FDS_VIRTUAL_PAGES( and DFU_APP_DATA_RESERVED ... (more)
I have an application that has to be ported to the newer Softdevice version. I've already ported my application to the SDK 13 and tested it with the new Softdevice v4.0.2.
I found that topic where ... (more)

I have an application based on SDK 11 and Softdevice v2.0.0. Also there is a legacy bootloader from SDK 11 for performing DFU.
I am wondering whether it is possible to perform DFU of my devices in ... (more)
I'm checking whether SDK 13.0.0 secure bootloader dfu can proceed correctly with iOS DFU library if the process is interrupted because smartphone application is restarted, or ble connection is lost, and so on.
I have tried ... (more)
I'm using nRF PWM Driver and I didn't find the way, how to invert logic of PWM. I would like to reach this behaviour:
I´m currently developing ble peripheral application for the nRF52832 with SDK v13.0.0. I need to have a secure connection between the nrf and android or ios mobile device and i figured that whitelisting with the peer manager ... (more)
I am trying to upload a bootloader to an nRF52832 chip. (This chip is on the ruuvitag and is programmed through their developer board).
I got the bootloader working on the DK but when I tried to upload it to ... (more)
I'm currently in the process of integrating unit testing into our firmware development process. I'm trying to execute on-target tests with the Unity test framework, using the Nordic-modified version provided in this post.

I implemented a function to add characteristics to a service, but I'm having a problem when I add notifiable characteristics. I pass a set of flags to my function, and when I set the NOTIFY bit,
sd_ble_gatts_characteristic_add returns ... (more)
I am writing a boot loader which does not need to use the soft device as the image is being transferred over an SPI interface.
I have merged the softdevice and my application code together to make a single ... (more)
Using SDK 13 FDS, I store 6468 byte, that is 1617 words, including FDS header. Of course this size is total. In detail in byte size, this size consists of
(12(header)+ 576) * 7 (12 + 774) * 1 (12 + 691) * 2 ...
I have an application where the DFU of a NRF52 is performed by another microcontroller via a serial port. Once the DFU is complete, the microcontroller turns off the entire system (including the NRF52). The issue I am encountering ... (more)

Any update on possible when Nordic can update the Plugin to support SDK13?
I was informed that the Nordic Semiconductor v1.2.2 plugin does not support SDK13.
Although I see there is a description under SDK13 that indicates it works. Here
Hello, I have problem when trying to use non default pins for uart.
This is what i got:
UART:WARNING:Function: nrf_drv_uart_init, error code: NRF_SUCCESS. UART:INFO:Transfer rx_len: 1. UART:INFO:Function: nrf_drv_uart_rx_for_uarte, error code: NRF_SUCCESS. UART:INFO:Transfer ...
I've built a ble app with a custom protocol, but am struggling with storing bonds, when running under freeRtos.
What I see:
We've stumbled upon a weird behavior on iOS making the smartphone unable to reconnect to our wireless device after a DFU from SDK11 to SDK13 (nRF52832): the notification subscription or char write makes the app crash. Once restarted ... (more)
I would like to include multiple p_chunks in one record. How do I do this? I've only seen examples with one chunk per record, but fds_record_t.data has a field called number_chunks. My uncertainty stems from the fact that ... (more)
I am just using the SDK13 on the nRF52832 together with the experimental BDS example (I modified it to the point where it seems to be working fine so far).
