Hi,
I faced with an initialization issue of combination two features: MCUMGR and UART_ASYNC_API. I get a crash right after the FW starts. It looks like the SW configuration...
Hello everyone! I'm currently working on a custom PCB designed specifically for drone communication . In my design, I'm using the nRF52820 as the main microcontroller and...
I checked the nrf52832 manual and found that both XC1 and CX2 are analog input pins for the 32Mhz clock pin configuration. The reference design for both uses 32Mhz crystals...
Hello, I need to configure and compile a sample to send an audio stream (mp3) to the I2S interface.

Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hello,
I'm looking for guidance and understanding of how to properly use the KMU and ITS for secure key storage of a key generated on device.
I see that typical ITS use...
Dear Sir/Madam,
I have a sensor prototype board using nRF51822 for Bluetooth communication and I am now working on its firmware. I have installed MDK version 5.16 and...
Dear sir,
Sir i am using MDBT42V module. I want to know that whether the SCL & SDA pine are internally pulled high in this module ?

Hi,
I have a problem where I am getting NRF_ERROR_RESOURCES errors 2 out of 3 times when sending notifications from my peripheral to my central. I think this is caused because...
I have designed a custom board with a TF325J32K7680 32KHz clock with +-50ppm tolerance, for the 32MHz I am using the CX2016DB32000D0WZRC1 with +-40ppm tolerance.
Simple...

Hi There,
I currently using PCA10040 development kit for my project. I tried to merge with \nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral\ble_app_blinky\pca10040\s132...
Hi
We have a product with Nordic nRF9E5 coupled to Texas CC1190 amplifier.
We are seeing transients at start and end of TX; worst at end. We appear to be non-compliant...
Hello, we are using SDK 5.2.0, SoftDevice 6.2.1 S110 on the peripheral side and S130 on the central side.
We have implemented a serial data link between the two, the central...
I have made a custom PCB with the nRF52832, following the circuit reference, I used the C3 and L1 for tunning the antenna. Instead of a chip antenna I placed a wire in the...
The NRF_LOG library apparently uses memobj, which uses balloc. I assume that means I need to add some blocks in my sdk_config (i.e., MEMORY_MANAGER_SMALL_BLOCK_COUNT, etc...
Hello Guys,
I have some measurements for the determination of the maximum range and the energy consumption. The experiment is based on the ATT_MTU throughput example, nRF5_SDK_14...
Hi,
We have a BLE peripheral device that is used as a mouse/keyboard (nRF52832 SDK 14.0)
The peripheral pairs with most central devices just fine (including Mac and PC...
