I am trying to get a good handle on the difference in average power consumption between BLE point to point and Zigbee on an nRF52840. We have battery powered products and...
Hi, For my project, I need to design a BLE packet sniffer which scanning the 40 channels. Therefore, I need 40 dongles are connected to a computer that can read and transfer...
I am writing code to get a nrf52840 DK to associate with an existing 802.15.4 coordinator using the 802.15.4 API module within SDK 15.2.
I've called "mlme_scan_req" and...
Currently, I am able to use Mqtt Publisher or Subscriber with only one Nrf52 device. I can ping to the device with link-local address.
I am using Nrf52832 with SoftDevice...
Hi everyone,
After days of figuring out how CMake works, I try to write a CMakeList.txt myself, and decide to put my progress on this community. Right now, using CLion with...

Hello everyone,
as indicated by this question https://devzone.nordicsemi.com/f/nordic-q-a/35692/adding-nrf52-dk-to-github-mesh-demo-for-thingys/138327#138327 I am trying...
Hi
I'm having a strange behaviour when using the TWI HW peripheral for reading from an I2C device. My application tries to read one byte from a register in a I2C device...
Hi,
I'm done with the hardware interface of my current project.
Right now I have a service running with a custom UUID, by writting this characterisitics you have access...
Hi,
I'm having the purpose to use nRF51422 /ANT to connect a relatively data hungry ANT device. The nRf51422 specs expose three programmatically available data rates : 250...
Hi,
I've written a nRF51 SWD-JTAG programmer.
I want to enable it to check for minimum softdevice version and error out if a too-old softdevice is found.
It is easy...
I want to communicate four same devices with different hosts. i know that one host can communicate to seven devices and also a device is able to speak different hosts . i...
Thanks for the response. As a test, I loaded the same code onto a PCA10004 and it seems to work as you described. A breakpoint at 217 does get triggered when it receives data...
I have been perusing the source to micro-esb, and it appears that it wants exclusive access to the NRF_RADIO interrupt(RADIO_IRQHandler) and things are designed so that only...
Hi,
i need to save an array of 50 kB on the nrf51822 flash. I only need to read the data stored in the array. I come from the PIC micro world where i simply need to initialize...
Hi,
On peripheral side i have S110 device with ble_bas service and custom base service. Both have notifications.
On centrasl side is S130. After discovering services i enable...
I want to use the pca10001 to communicate as a master to an accelerometer, but when i use the function spi_master_open i get a NRF_ERROR_NOT_SUPPORTED error. I get no clock...
Hi everyone.
I am working with nRF51 to make two BLE device, One act as cetral and another as peripheral.
I have implemented almost functions that the two devices are...
Hi,
Do all NRF51822-DK (development kit) have the same silicon build revision? If not, which distributor should I approach for the latest revision and is there a specific...
I have encountered a problem with the IAR linker where I run into a 32k code-limitaion, even though I have a licence with no limitations. According to IAR, the problem may...
I was playing around with examples and decided to implement a custom service that sends the RSSI as a single-byte characteristic value. Here's the init function:
