How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
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...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
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...
Hi all,
I need to change the device name frequently to show button status.
So remote device can see button status without connecting to device.
Is there any way to...
Hi guys,
i have a service with more characteristics and more states. Not every characteristic should be available in each state. Thus there are services which are just...
Using the S120 soft-device in the Central role, there does not appear to be an
example or documentation describing how to scan for a 128 bit UUID service.
Has anyone tried...
Apparently there is some limitation on length of the paths with Keil. The paths are specified under "Options for Target" --> C/C++ --> "Include Paths". Due to this limitation...
I downloaded the nrfgo Sdk for the nrf24lu and nrf24le. In the projects folder there are several examples, two of which are of interest. The first is entitled "bootloader_32K...
Hi
I'm having a strange behaviour when using the TWI HW peripheral for reading from an I2C device. My application tries to read one byte from a register in a I2C device...
Hi,
I'm done with the hardware interface of my current project.
Right now I have a service running with a custom UUID, by writting this characterisitics you have access...
Hi,
I'm having the purpose to use nRF51422 /ANT to connect a relatively data hungry ANT device. The nRf51422 specs expose three programmatically available data rates : 250...
Hi,
I've written a nRF51 SWD-JTAG programmer.
I want to enable it to check for minimum softdevice version and error out if a too-old softdevice is found.
It is easy...
I want to communicate four same devices with different hosts. i know that one host can communicate to seven devices and also a device is able to speak different hosts . i...
Thanks for the response. As a test, I loaded the same code onto a PCA10004 and it seems to work as you described. A breakpoint at 217 does get triggered when it receives data...
I have been perusing the source to micro-esb, and it appears that it wants exclusive access to the NRF_RADIO interrupt(RADIO_IRQHandler) and things are designed so that only...
Hi,
i need to save an array of 50 kB on the nrf51822 flash. I only need to read the data stored in the array. I come from the PIC micro world where i simply need to initialize...
Hi,
On peripheral side i have S110 device with ble_bas service and custom base service. Both have notifications.
On centrasl side is S130. After discovering services i enable...
