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,
Is there a possibility to read the state of the gpiote pin? (is it high or low). Is there any function or any other way to do that?
I'm changing the gpiote pin via...
Hi,
I made a own service for a rotary dail in a peripheral(S110). This service send the speed, direction and a counter (all uint8) of de rotarydail in separate characteristics...
Hi Everyone ,
We were using nrf51822 rev1 IC for our project and now it is changed to nrf51822 rev3 . Previously we were able to detect the chip in nRfgo Studio on our...
I am looking for a device with support for the 4.2, long packets (up to 255 bytes) feature. I see that the nRF52 is a 4.2 device. But for what I understand the optional long...
I am using s120 for central device, and my central device connects to multiple BLE slaves. After connection, some slaves may lost connection due to power off of that device...
I want send ble bond connection request from raspberry pi to nrf51882.
Can you please let me know which ble libraries I need to send central ble bond request to nrf51882...
Hi,
My goal is to capture on gpio burst infrared proprietary "messages" composed of multiple "bits".
The Length of each bit is around 100 to 200us.
Initially I planned...

On a BLE_GAP_EVT_CONNECTED, I'll send some data to an attached microcontroller via UART. The code will expect a response of that data, all while being inside that BLE_GAP_EVT_CONNECTED...
My application involves the Nrf52 using softdevice and a slave only SPI ADC running at approximately 26khz. The ADC has a pin interrupt to indicate data ready. There seems...
Building nrf_delay.c (or anything else including nrf_delay.h ) with NRF52 defined produces:

Hello Nordic community:
I've read about Serialization in the nRF51 SDK doc and would like to prototype an example with it.
I saw a notice of it being removed post 7...
Hi,
Is it possible to get a more detailed description of the GPIO block than what is available in the reference manual? Specifically i'm interested in how the disconnect...
