I want to store the CRC of the current firmware in the flash, for DFU purposes. Almost all of the threads I've seen so far reference the pstorage API but it's no longer supported since SDK12. There ... (more)
Hi to everybody,
I am working with a custom board based on the nrf52832, while trying to integrate to my existing application the DFU functionality I am having problems when I try to change from app to bootloader through Buttonless ... (more)
I'm working on an UART application which uses experimental_bootloader_secure_serial bootloader. I've done a similar thing before with SDK-11 (though not a secure DFU) and after getting through building a secure bootloader, signing, etc. I was able to ... (more)
I'm currently developing an application on nrf52832 that'll use SAADC low power to fetch battery voltage level and report that value on BLE advertising data. I've adapt github example nFRF52-ADC-examples to the following:
#define REFERENCE_TO_MV 0 ...
I'm currently experimenting with the dual-bank bootloader in SDK 13.1. According to the documentation, if the new application can be activated, it is copied from bank 1 to bank 0.
Where and when does this happen? I ... (more)
when looking at
nrf_drv_i2s.c in SDK v13.0.0, the description of nrf_drv_i2s_start() states that the parameter
Size of the buffers (in 32-bit words).
I don't generally like mixing up size, length, count, and capacity ... (more)
i am writing an application which uses the SDK13 peer manager library for bonding. The Nordic chip is acting as a peripheral.
Is there an easy way to prevent the peer manager from saving every change to flash memory ... (more)
I am trying to add saadc sample code to ble_blinky sample code. But I faced a problem. It seems that the sdk_config.h file is not recognized by the sample code. and I got this errors:

We're seeing an issue where a dfu package containing SD+BL+Apps gets stuck on iOS nrfToolbox during DFU process after it updated the first part 1/2, which is BL+SD. The same dfu package works on the ... (more)
I am using saadc sample cod of SDK13. Changing some parameters based on the analog input, the example is sucking somewhere where I have not been able to find it.
Searching for a solution, I wanted to use DEBUG ... (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).
Now when using uint8-array as data-type for a writeable ... (more)
Just ported from nrf52 project using sd132 v 5.0 to sdk13 release sd132 v4.02
Changed the necessaries and changed to the new ret = nrf_drv_spi_init(&spi, &spi_config, NULL, NULL);
I can no longer get the spi to work. It ... (more)
My question is basically a duplicate of this one https://devzone.nordicsemi.com/questi... but for s132 (v4.0.2) instead of s130. Is this documented anywhere?
We recently moved from SDK11 to SDK13. We run out of memory when adding custom services & chars to the S132 v4.0 softdevice. Increasing the app start address in the linker file just causes the app to crash.
How do ... (more)
hello! Our products will use STM32+nRF52832 and will be support ANT+BLE,but the SDK13 have not example that about softdevice s332 v4.0.2.so our company hope you can give us help.we hope you can provide ... (more)
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'm migrating from SDK11 to SDK13. My custom service is based off Heart Rate Service, so I started from the new SDK13 example of HRS, and updated all the initialization code following the new example.
Changed: ble_cg.common_cg.vs_uuid__cfg ... (more)
I'm using nRF52 + s132v2.0.0 + SDK11.0.0. I want to be able to update to s132v4.0.2 (or so) + SDK13.0.0 via DFU. I'm planning on modifying the bootloader start address to 0x77000 with ... (more)
I'm using nRF52 + SDK11.0.0 + s132 and have a couple of questions on DFU.
I recently migrated our code to the SDK 13 (we use the nrf52832) and now the function:
uint32_t err_code = ble_radio_notification_init(6, NRF_RADIO_NOTIFICATION_DISTANCE_5500US, on_ble_radio_active_evt); APP_ERROR_CHECK(err_code);
Returns error code 8... I can't find any example or similar so I ... (more)
If I am programming a BLE Server device, and I configure a characteristic with BLE_GATTS_VLOC_USER and queue a notification with sd_ble_gatts_hvx(), how soon can I update the characteristic value?
With BLE_GATTS_VLOC_STACK, I know you can call sd_ble_gatts_hvx() and update the ... (more)
I am using nrf52832 for our product. Recently I updated stack and sdk from s132v2/sdk12.1 to s132v4/sdk13. However, I see a new characteristic under Generic Acess 0x1800 primary service: "Central Address Resolution", UUID 0x2AA6. As ... (more)
I have a device in the central role that connects to a device with a specific name. I then do a
db_discovery_start to get the handles of two of the characteristics. However, it takes a while for the

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
Hey, I want to save stuff to flash under the same id and key which should be no problem as shown in the documentation. But when I save it and retrieve the data only the last saved data is in ... (more)
I am using a nRF52832 with SD S132 V4.0.2 ion SDK13.
My application currently uses TWI, SPI and BLE and also 1 wire (which is based on delays). Everything works fine. The 1 wire is used ... (more)
We have these Dev Kit Nrf52 and also Nrf51 Bluetooth Smart Beacon Kit. For our application and for the simplest user experience we would like to benefit from update via OTA. And for a design and Security point of view ... (more)
