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...
Hello Nordic,
My goal is to control a small device with NRF51422 without any other additional controller. So I’ve developed my own PCB and I’ve used the example ble_app_uart_s130_pca10028...

Hi,
I have an nRF52 chip that has likely exceeded the flash endurance limit.
I am observing that after an ERASEALL, not all bits are erased, but after retrying ERASEALL...
Hi, does somebody know why in Segger embedded studio program goes to ses_nrf51_startup.s line 35 ISR_HANDLER NMI_Handler and sits there. I'm trying ble_app_cscs_pca10028_s130...
I only have Bluetooth 4.0 scanners and I bought nrf51 dk with 51422 device (10028) that seems to work as 4.1 Bluetooth. I tried sdk12 s130 and sdk8 s110 beacon examples my...
Hi,
I'm trying to program the bootloader together with an application+SD132 3.0 on the nrf52, but my device gets stuck with the bootloader when I finish programming it...
Hello, I used s130, nRF5_SDK_12.1.0_0d23e2a, SoftDevice 8_9_0.
Is there any example to study the central bond?
I use the examples->ble_central->ble_app_uart_c, the following...
Hi All,
I have hardware setup which has four or more beacons in peripheral mode at particular radius ( approx 10 m) and have a beacon in central mode.
The central beacon...
I'm using the Nordic as a BLE solution, and it is just passing along data through the UART to another chip through the UART. However, I'm not sure how to just pass the data...
Greetings,
I am using pynrfjprog (9.0.0) to write a HEX file to an nRF52 device on the nRF52 DK. I am wondering if there is an easy way to verify the write using API.py...
We're looking to implement buttonless DFUs with the NRF52 and are a bit confused how to send 0x01 to the control point of the service. Is this a control point that is already...
I have tried to export a very simple mbed program (blinks LED1 and LED2 and writes to Serial (USBTX, USBRX)) with no success. I am running on an Ubuntu 32 bit distro. This...
Hi,
Is there an example for the Sleep modes and 2Wire on the nrf24LE1 with the SDK? Just found some 2Wire examples with a modified HAL which doesn't seem to work for me...
I'm trying to get the I2C on the nrf24LE1 working. I'm using the modified Library from nAN-20. It doesn't do anything. Can't see anything on the oscilloscope. It's an nrf24LE1...
Hi,
I'm using nRF5_SDK_12.0.0_12f24da and s132_nrf52_3.0.0_softdevice to do the mutilink and it's almost ready. We want to do the OTA on it. I think the mutilink is working...
