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...
Hi, i am currently modifikat a working ANT-System (Master with multiple Slaves) with the NRF51422 and Softdevie 1.0 to be robust against in band disrupters. My idea is to...
I have an application based on the ble_HID_keyboard_template (uses STM32F072 instead of Arduino). The first time I pair my iPhone 5 (iOS 8.1.1) with the nRF8001, everything...
Hi,
I'm using nRF51422 with S310 and ble_app_hrs example application.
Thus I can simulate a Heart Rate Sensor with the board and get data on an Android phone with the...
Hi all! May I use another quartz instead of 16 MHz? Will the output frequency equal to 2.4GHz/16, if I will be use the 1 MHz quartz? Or IC will not work? Is it possible to...
I need to evaluate the real consumption of current for BLE events on RF81822. The HFCLK is 16MHz and the 32kHz clock is external.
S110 Soft Device Specification V1.2 document...
Hi, I am using S120 1.0.0 and SDK 6.0.0. Learning the sample project 'ble_app_multilink_central'.
I already got a peripheral device with NUS service. The central device...
I am new to this great platform and am struggling with getting my PIR sensor connected to my DK. I wonder if some of you experts could give me some pointers on how to go about...
Hello, I build a BLE 6LoWPAN environment on my raspberry pi with Kernel 3.18.3 and connect a BLE Dongle. The BLE Node is Arch BLE ( www.seeedstudio.com/.../Arch-BLE-p-1998...
Hi, I have two different types of nRF24L01+ modules, both behave differently.
The "troublesome" module always has TX_DS asserted after a transmit, which is the same behavior...
Hi,
I am using the SPI Master 1 to control an EEPROM. I used the spi_example project to help get the code working. It all works fine if the code that initiates the SPI...
We have designed a differential antenna for the nRF51822 CEAA chip.
Each of the RF output connects through a matching circuit to each one of the two 50-ohm to ground end...
How to setup MQTT for CloudMQTT? I have working raspberry PI I can ping and connect to device when follow the user guide. Now I like to try MQTT example but don´t know how...
Is there a list of every interrupt these functions effect. Specifically I am worried about
static void ble_evt_dispatch(ble_evt_t * p_ble_evt)
My assumption is that...
Is there any S110 demo with good communication between periphera and APP in phone side in SDK 6.0? It means that data channle works well from 51822 to APP and APP to 51822...
