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
I need to define a buffer (array of structure) in order to buffer readings. If i have more RAM I should create a bigger buffer if I have...
We're using the nRF52832 as a peripheral and server. A central and client (tablet) connects to the nRF52832.
Yesterday I noticed that sometimes the tablet will try to perform...
Hello,
I am using nRF52832 DK PCA10040 v1.2.4, SDK_15.3.0, S132 SoftDevice and Segger for flashing the image. I am using ‘ble_app_blinky’.
What for this macro HWFC...
Hi, I'm looking for a PCB antenna design for nRF52832 based on 0.8 mm thickness four or two layers stack up .
I found some examples but based on pbc of different thickness...
Good morning,
I'm designing a new product based on the nRF52840 device (s140) and power consumption is one of the key parameters for my project.
The equipment (peripheral...
I'm debugging some corner-cases with my own DFU process and Bootloader. I believe I hit a race condition in which sd_mbr_command() was called before the source of the new...
I am trying to make a service discovery on a peripheral device using a nrf52-DK (pca10040). I built my project around the multi-discovery example from SDK 15.3.
When performing...
Hey all,
I'm trying to replace the nrf_cli_uart transport layer with the CDC ACM equivalent (nrf_cli_cdc_acm), since I have an nrf52840 dongle and can't use the uart libraries...
