Hi,my friend,
Now,I use nrf905.Situation is as follows:
I use the NRF PCB circuit of data manual.Nrf905 work, often loss of data.
1.The Product host is to use the stick...
Hi,
I want to use the Blend Micro with more security. I want use a passkey for the Bluetooth connection. For example through the iOS Device.
Is it possible? Static passkey...
How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?

Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
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...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
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...
