We are building a new version of a small device with the new nRF52832. Its only external connection is a micro USB plug that we use for charging - we do not need it as USB data interface. But would like ... (more)
I'm trying to use nRF52 twi with the MPU 9250, I consistently get NACK responses from the 9250. I have the 9250 working with an Arduino.
The function I'm trying to use to transfer using twi is nrf_drv_twi_tx ... (more)
I would like to design a product based on the nRF52832 chip. The board should have an accelerometer, a charging circuitry for a LiPo and some additional components (switch, LEDs). In order to reduce development time, have a ... (more)
I am done with TI and the new IDE and Stack 2.2
May be anybody can point me to the right IDE and chip to replace my TI CC2640 4x4 designs to Nordic semiconductor solutions.
I would ... (more)
I have a pretty simple problem but I can't get it right. This is what I want to do:
T=000, PIN_x = 0<br> T=004, PIN_x = 1<br> T=100, call a routine<br> T=543, Start ... (more)
I am migrating from nrf51 to nrf52. Using SDK12.1
On NRF51, I used the PWM Library to use 2 buttons on the DK to dim up or down onboard LED1 (called OUTPUT_LED). It worked great (not sure if it ... (more)
Has anyone using nRF24L01 raw (CRC turned off) mode. I try to turn off the CRC (the data sheet offers this option), then I start to miss packets. Once I turn on the CRC, I got every packets I sent ... (more)
I have a NRF51 talking through the UART to another uC, and I'm trying to log messages through Segger RTT. Everything works normally until I start to send some data through the UART, and then RTT stops working, although ... (more)
hey I have a nRF51822 eval board and I want to use it as hid keyboard to send some media key such as vol+/- play/pause, etc. I have used the example code ble_hid_keyboard and it works well to send ... (more)
I am trying to send lots of data through radio (basing on old micro esb project from github, but heavily modified). I need to keep radio IDLE (not DISABLED) when not transmitting, because ramp-up time sometimes is too long and ... (more)
Hi , This is the first time I am using nRF52 and I don't have any experience about Antenna design. Here is my question: I am using nRF52 CIAA variant and planing to use PCB antenna. when I see the ... (more)
I would like advertise for an unlimited time. Why value 0 in ble_gap_adv_params_t::timeout don't work ? Device don't advertise anything. It works fine with a positive value ( <180)/ I'm using S110 stack v6 and the last ... (more)
Is there any guideline on how to setup and use the UARTE on nRF52 ?
We can not convert Altium File to DipTrace or Eagle File. We need those files asap. I'd be thankful if you could help me in that issue.
I implemented nrf51 flashing through SWD (external MCU is used). After first flashing and reset when we enter debug mode on SWD second time we have a busy state (NVMC_READY (0x4001E000 + 0x400) is set to zero) from NVMC ... (more)
We are using SDK 11 and SD v2. I did a search for an answer to this question, but couldn't find one that addressed it fully but what I gleaned is that this may not be possible with SDK ... (more)
hello there i want to add uart driver in beacon project. i have added it. but my project is not working. can you tell me?? what is my problem??main.c
Hi everyone! I made some board with 51822 (128k, 16k). I have only 20kb free if I use the S130. The questions: a) I only will sent data to a mobile. Can I use the S110 that it's more ... (more)
I am testing the ble_peripheral example of ble_app_uart (SDK 12, soft device 130), this has been asked at a lot of places that the MTU is limited to 20. But then I implemented my own code snippet to send ... (more)
I'm testing latest examples on 10040 (SDK12 S132). I want to get autoConnect working on Blinky example with nRF Connect app but I'm unable. Has anyone tried this?
I modified the blinky_freertos example from SDK 12 slightly to perform the following:
I have one timer and one task. The task blinks a LED and then suspends. In the timer callback function (one second period) I resume the ... (more)
