I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
Hi,
I tested the nrf beacon application, it allows only the beacons with company identifier 0x0059 (nordic's id). But i need to modify it to support all the device, how...

Hello,
I am designing a custom PCB with NRF52832 IC. According to datsheet, required specification of inductor L1 are:3.9nH, 0402 package, 5% and a High-frequecy chip inductor...
Hello,
I did some power measurement on the nrf52 DK with the Nordic profiler kit and the result was way more than what we could expect from a nrf52 (about 1 mA). Even in...
I am working on the ANT connectivity for a product we've developed, called RunScribe [a shoe-worn running sensor], and am seeing some issues on Fenix 5 watches with our ANT...

Hi,
I'm quite a beginner to this whole nrf52832 world and I'm trying to read some data from a flex sensor wired in series with another resistor connected to VCC now I understand...
In brief our problem with rfx2411n is that rfx begins to draw 200ma current without any reason. Rfx is powered down, powered from 3,0v. And suddenly something happens and...
I have a device that runs with nRF51 chip with the NRF UART Service (NUS).
I have a Raspberry Pi 3 and I want them to communicate.
The device requires an authentication...
My question is related to peripheral device only. I have implemented an auto connection interval negotiation algorithm which works as expected and negotiates connection interval...
Hi! I am building an android app for my project. I am using Proximity , UART and DFU from nrfToolbox app. I have 3 buttons on my home screen dedicated for each of them. I...
Hello sir,
I have completed PCB design of custom nRF52832 board. Can i use following component instead of recommended part No in reference design. I have also mentioned...
Hello ,
I would like to design a custom board with nrf52832 IC and CP2102 for communication with PC serially. Unfortunately nrf52832 doesnot have Rx/Tx pins for interfacing...
Hi community,
for our application (nrf52832 / SDK 12.2) we need to store data received via BLE. The received data is a 25 kB binary blob which by design will be chopped...
Hi,
i am checking NRF52840 for USB behaviour.
I'm using example usbd_cdc_acm.
But USB receiving stucks after few bytes (between 0 and 50) and does not receives nothing...
