Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
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.
When...
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...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi
in the communication with an SPI peripheral device, a communication cycle might take up to 5 ms.
It is implemented as a blocking function, meaning that app_sched_execute...
Hi all! Several weeks I've tryed to implement code for my wireless temperature sensor based on nrf24le1 and ds18b20. In datasheet said that in memory retention mode the power...
Hi,
Is it possible to send a advertisements for a single (or a fixed number of) Advertising Events? I need to control the number of Advertising Events "sent" for a mesh...
Hi, I'm looking to build a simple ANT+ application. My only asset for this project is a background in C/C++. I'll need to learn/relearn the basic electronics and protocol...
Hi Nordic,
I have an application that perfectly runs in the nrf51DK but that does not work in my custom board. In my custom board everything else works (i2c, leds lighting...
I understand that in order to trigger bonding procedure you need to read/write a secure characteristic.
I am using the nRF Connect application on IPhone and trying to see...
Hi all,
I need to take samples of a period of two periodic signals and made some DSP processing with both signals.
I need at least 64 to 128 samples per signals.
I...
Greetings,
In Bluetooth 5, there is a new mode of advertisement called periodic advertisements where the advertising device can periodically advertise over the 37 non-primary...
I have a design running on nRF51 that I'm evaluating to run on nRF52. One important characteristic I'm looking for is to store it for long period with a minimum power consumption...
Having some problems upgrading the PCA10056 to firmware 1.0.1 as stated in the getting started. After downloading the only file I found I can no longer connect to it.
Can...
I've been trying to use nRF52 (PCA10040 board) with SDK 12 to read data from max30102 through I2C.
I used non-blocking read and this is twi init function and event hander...
According to S130_SDS_v2.0, I can choose to return NRF_RADIO_SIGNAL_CALLBACK_ACTION_NONE after NRF_RADIO_CALLBACK_SIGNAL_TYPE_EXTEND_SUCCEEDED to stop extend more timeslots...
I want to trigger SAADC by PPI between RTC compare event and SAADC sample task. Is it possible?
In the SAADC example (SDK 12.2.0), a timer is implemented. In function nrf_drv_timer_extended_compare...
Hi!
Which project do i need to look at in order for 5 devices which are NFR52 to send data each other
There is only one center in multilink project and other devices dont...
hello there i want to use AES in nrf51.
i want to encrypt nrf51's advertisement data . and decrypt using android app.
i have some confusions
(1) should i use nordic's...
