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...
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'm using s130 as softdevice for nrf51822. I program the softdevice with the official s130 hex file. According to the hex file, there is no data at address from 0x7c0...
We're working on an application that needs ultra-short range BLE, on the order of 50cm radius or less. I've found little discussion anywhere on that topic, likely because...
I notice that the dongle has a 3.6V-5.5V input and a pin that sais 3.3V, I measured 3.3V on this pin so I was curious if I could run an IMU unit and an i2c/spi bridge requiring...
Hii all
I am trying to port the experimental/bootloader_signing project to gcc I made changes in the project accordingly, so now its working. I can able to flash application...
I connect a GPS module to nRF52 DK and connect nRF52 DK to my computer once more.
GPS module ---> nRF52 DK ---> computer. (like this)
So I want to do NMEA parsing like...
Dear All,
I am sorry but I have to ask this question here, I searched and red trough the forum, tried the suggestions, nothing works.
Basically I want to have a HID device...
I use softdevice 6.00, size is 80K Byte. I use the chip NRF51822ab,and configurat the irom start at 0x14000,size 0xC000, IRAM, start at 0x20002000,size is 0x2000 ,in keil...
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...
(I understand my question is similar to devzone.nordicsemi.com/.../ , but I would like some additional clarification not provided in that post.)
