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,
I am using Timer_2 with two CC registers configured, 2 PPI channels (one for each CC register in the timer), and one GPTIO_TE to make a PWM to control dimming on...
hi,
my nrf51822dk was downloaded s110 hrs demo,and it was advertising,i used a ble sniffer dongle to get the advertising data.the AdvData is "0B 09 4E 6F 72 64 69 63 5F 48...
Why is it a standard in nordic-supplied code to initialize structs with memset like so? An example would be:
ble_gatts_char_md_t char_md;
memset(&char_md, 0, sizeof(char_md...
//Edit:
So Hung Bui just told me in another question, that there is indeed a buffer of size 6 or so?
How can I decrease that to 1 (i.e. disable it) so that only the latest...
I have the nRF52 DK and cannot determine the silicon revision on it. Is it the 'Engineering A' revision and therefore is subject to all the Errata that is currently published...
there are 3 modules to test(A1,B1,C1)
*2. A1 connect with B1(B1 is master, A1 is slave), C1 is power off, B1 as slave attempt to connect C1 with BLE_GAP_ADV_TYPE_ADV_IND...
I need a PWM signal as outoput from the nRF51-DK. And I do need the softdevice. So I decided to pick the code from the nrf51-pwm-library-master and add it to my project(SKD...
Why I will restart the ADC is used to measure the voltage is greater than 1.2 V
void battery_start(void)

I just assembled my first nRF51822 board and I was able to program it using an IDAP-LINK and a blinky program compiled with the Eclipse/GCC toolchain flashed via SWDIO/SWDCLK...
Hi all,
Due to the updates file structure introduces in SDK 7.0 I'm trying to figure our where everything has been scrambled to. Here are the items I'm struggling with...
