Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.

Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hi,
On a NRF52840, I try to perform `x` SPI transactions of 3 bytes each using EasyDMA Arraylist feature fully controlled by hardware. The CS must be toggled between each...
Dear Nordic Experts, The firmware is based on nRF5 SDK for Mesh 5.0.0 with nRF5 SDK 17.0.2 and Softdevice s132 7.3.0. It runs on a nRF52832. When provisioning, it sometimes...
Hello, All
I am trying the scan_adv example, and use my phone to scan the advertising packet, unlike other peripheral examples, I found that it appears multiple time with...
ncs v1.9.1
Reference nrf\applications\serial_lte_modem\src\twi
This example does not see how to configure the pin.so how to config SCK and SDA Pin?
Thanks!!!
Is it feasible for me to use the 9160 as ble-host and 52820 as ble-controller using just TX and RX lines? (no request or ready lines) My setup is NCS v1.7.0, custom board...
I see that there is definitely support for where a user would cancel the USB host's request to suspend inside of app_usbd.c here's line 1246:
You can clearly see that it...
Hi,
I know that a GPS receiver can can use the Doppler effect to get an accurate velocity measurement. More accurate than the accuracy for position.
However, from my tests...
Hi,
I'm facing the mqtt error shown in the image below "E: mqtt_connect, error; -111" when I try to establish connection between the nRF9160 DK and AWS Cloud. I've double...
Hi,
I am required to develop a new model, upon design considerations I considered that my main BLE-Mesh model will have 3 independent sub-models each designed as per functionality...
Sorry if this is a repeat ticket. I've done some searches and they result in information around Zephyr and RF Connect SDK Git repos and West usage to manages related source...
Hello,
I am using MQTT+TLS on nRF9160DK. In the development stage, I followed this link https://devzone.nordicsemi.com/guides/cellular-iot-guides/b/software-and-protocols...
Hi,
Mesh SDK: v5
Using nRF 528232
I am trying to implement a low power node feature on an existing PIR sensor code. I have added all the necessary functions and macros...
I started off my project with the Zigbee light_bulb sample, and I added some new functionality that needs to manipulate various GPIOs. These GPIOs are neither buttons/keys...
I am trying to find some rough estimate of power consumption on nrf9160 in nb-iot and Cat-M mode.
We are going send about 600 bytes every 15 min, and would like to know...
I have a custom model that is declared as follows
