Hi.
I'm using nRF52832 with MPU9250 IMU sensor to gather accelerometer, gyroscope data for mobility.
MPU9250 sensor is connected to nRF52832 via I2C line.
When...
I have read that choosing shorter connection interval reduces the communication latency at the cost of increased power consumption.
But shorter connection interval will...
I am scanning for advertisements and in scan_evt_handler() in the case NRF_BLE_SCAN_EVT_NOT_FOUND, I am printing the packet received using NRF_LOG_INFO().
I have also implemented...
Hi,
I would like to connect two external SPI flashes to the QSPI interface on my nRF52840. I see that there's only a single CSN pin that can be configured. Is it possible...
Hello,
I'm currently working on creating a custom characteristic so that my client can read a set of data from the server.
My intention is to have a server gather information...
Hi,
How do I measure the length of the created advertisement buffer? I want to add two UUIDs in the packet and the device is resetting. I guess the length is the issue...
Hi,
Is there any kind of dependency tree for the libraries and drivers of the SDK (NRF5)?
I have been searching the Infocenter documentation but I haven't found anything...
Hi,
I am using the TWI scanner example from the sdk15. Board is NRF52840. I have a differential pressure sensor connected to the TWI input pins on the nordic board and am...
Hello!

Hi Sir,
According to the datasheet of 52840 (v1.1), in the ref. schematic, the requirement of 32M is +/- 40 ppm.
In section 5.4.4.2, for the frequency tolerance requirement...
Hello,
Please comment on the expected difference in achievable range using 20 dBm vs. 23 dBm output power. Any details, assumptions, questions, etc. would be appreciated...
Hi, I'm looking for a more modern transceiver than nRF24L01 + and that works for the same. I am looking for a low or ultra low power transceiver that allows the implementation...
Hi, For my POC I use nrf9160 dk. Nrf52840 is used for scanning ble devices and nrf9160 dk is used for sending data to mqtt server (very similiar to one of the examples with...
