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 am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
Hello, recently I've been going through SDK v12.2 and board documentation but I can't find any info about choosing which of board's antenna to use.
Simply, I'd like to know...
I am developing on a BLE Nano 1.5 and need to use PWM to make a beeping sound from a piezo buzzer. I am wondering which pins are capable of PWM. Here is the pinout diagram...
Hi

First of all I appreciate your help.I am using mesh example in https://github.com/NordicSemiconductor/nRF51-ble-bcast-mesh link .I can send data by providing connection with...
Hi Nordic team,
This problem bothers me for a very long time. I cannot find the root cause. I used nRF51822 IC. It uses SDK11 with softdevice S130 and bootloader (but I...
Using nRF52 with SD 132 3.0.0.
Peer manager uses fstorage to store information.
I need to be able to specify the address range which fstorage can use.
Is there a configurable...
Hi,
I have problem with both functions sd_ble_gatts_value on central device.
It works on peripheral, because there is my characteristics definition.
Now I have to read...
Hello,
I'm developing a BLE Application where I use the peer manager. My Goal is to use direct advertising after disconnection if a device already has bonded. But every...
I am using the SAADC on the nRF52832, SDK12.2.0, with it set to 12 bits and low power mode. I have enabled five channels which I run blocking nrf_drv_saadc_sample_convert...
Dose this capture from the Nordic Specification means that to read bytes from SPI i need to send before. Each byte i send i get a byte!!!
MLy case i have read only sensor...
I am using the nrf52832 with the s132 for a project in which I have a frame with 24 bytes that need to be transmitted through BLE.
I have followed the tutorials and I have...
Hi,
First I'd like to salute the great work done by you Nordic people for those open source and hardware.
I just installed the SDK 10.0.0, S120, gcc-arm toolchain, configure...
Hello, I'm a beginner with the BLE technology and nRF52 is a good tool to start with it.
Currently, I have a setup that allows a Raspberry Pi and an nRF52 to communicate...
Hi. I have a problem with programming brand new chips nRF51422.
I have connected: Vcc (1, 12, 35, 36), Gnd (33,34,13), Swdio (23) Swdclk (24).
