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...

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...
I download my elf file using SEGGER Jlink via Eclipse. The instruction pointer gets positioned on the Reset_Handler. But when I try to run the code after that, I get a SIGTRAP...
HI:
I try use pstorage_raw_mode to store data. According to the document description,first steps:
ble_stack_init() and scheduler_init(). Then, in turn, calls the function...
Hello,
I need a FIFO buffer for at least 20 arrays with 8 int32 in each... for use in an algorithm.. is there a more elegant way than just copying them all around each...
I'm using the mbed platform and have been battling hard faults as I try to find the best way to write with high frequency to SPI to update a series of LEDs while still allowing...
I'm migrating an old (but working) app from the S110 5.2.1 (SDK 4.X) to the latest SDK9/S110 8.0. I've read the migration doc, and I'm following the examples carefully (specifically...
Hi,
I downloaded latest version of SDK and all examples resented there are for nrf51422.
Can I use those examples for nrf51822?
I'm using ukeil and I can only select nrf51422...
Our chip seems to be running at ~500uA and I'm trying to narrow it down.
I'm doing periodic battery level checks on a timer using the ADC HAL. So at init I call nrf_adc_configure...
I use s110 send notification to s120 in 1 - 1with 7.5ms connect interval,but the data maximum data throughput is only 21.3 /2 kbps.how can i do to raise the throughput???...
i use s110 send notification to s120,and set connect interval with 7.5ms,but in actually the connect interval is 15ms!!I see s120 softdevice specification,s120 as client which...
Hi,here i met an issue that when i set address type in public mode by funtion sd_ble_gap_address_set(),and then the advdata packet data was all zereo.This project was created...
Dear ladies and gentlemen,
There is not much information about the RESET pin in the datasheet. I guess, it doesn't have an internal pull-down resistor, but when I look at...
Hi,
I have a problem configuring readback protection using boot.
It seams that the BOOTLOADER stops when trying to read some information from the softdevice if readback...
HI:
i want to use peripheral and central function.and i can switch it to work peripheral or central state when i need.which stack should i use.s120 or s130.
