we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...
I am try this at nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard
Firt I connect to Android device and keep one whitelist.pp_addrs and one whitelist...
What is the switching frequency of the DC/DC regulator in the nRF52832? The DC/DC is great for reducing power consumption, but I am worried about the switching noise getting...
Hello.
I am trying to save i/o lines on an 8-pin PIC, and planning to run an nRF24L01P with its CE pin tied to VDD. I am willing to power-down to get out of the RX mode...
Hi
I am using an Identive NFC reader/writer SCL3711 and their sample app to read tags.
In the sample app, through the debugger I can see that it is registering an NDEF...
hello, Nrf24LU (Rx) , nRF51822(Tx).
The Nrf24LU Can only receive one packet。
if I use this function twice , like this:
The Nrf24LU can receive Continuous.
I guess The...
Hi,
I use nrf51422 and integrated BMA250E for Pedometer,
Now I can count the step but I dont how to calculate the speed, cadence and stride length like below
static void...
Hi All,
From my firmware I need to send large ble packets say of 1 K to the phone.
Is there any library or example code for sending large packets. Currently I am splitting...
Hi,
Our application requires that we connect a nRF52832 to a Microchip PIC32MZ host via the Nordic parts UART (RS-232 at CMOS levels).
In a previous application, we...
Hi everyone,
I've been testing SPIM with easyDMA, using nrf_drv_spi. I'd like to flush a 6-axis sensor FIFO in one SPI operation (31 samples * 12 bytes = 372 bytes) but...
Hi,
I am working with the ble_app_uart (central and peripheral) example and they already run fine. Now I discovered that some button actions are already defined on the...
Hello,
I have created the simple software usign NRF51DK to make the led blink for 5 times by using while loop
just to make the other part of my software
my aim of this...
hi,i have a question.
i set the advertise type to BLE_GAP_ADV_TYPE_ADV_NONCONN_IND MODE, and i add scan response data,but i can't see scan response data.Why?
Hi,
I would like to connect nrf8001 to a Renesas microcontroller but I could not find any documentation on how to proceed with this step. The only documentation I could...
The ADC module requires that the output impedance of the connected voltage source be 1kohm or less (section 31.1.3 of RM).
Does the same restriction apply for the LPCOMP...
