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.

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...
Nordic,
I am using the BLE Shield v2 and the Arduino Due board to transmit accelerometer/gyro data to an Android tablet app that plots this data. I had this working fine...
First I noticed that nordic has already updated the andriod nrf toolbox app to use softdevice v7, which allows updating the softdevice, bootloader and application.
The...
Hello all,
I'm working on a library for NRF24L01+ and PIC micro.
Unfortunately there is something wrong. On the receiver side, the micro correctly detects that a packet...
Hi,
I am knew to BLE and I was able to ran succesfully the blinky project. Now when I load the soft device on and then try to download the hr example if says "Flash download...
How do you create hid information for a joystick and send it over BLE. Nordic doesn't seem to have
primitives for this (they have keyboard and mouse facilities). I'm working...
Hi,
I develop an application with the nRF51822 circuit. It is detectable with my smartphone, but not with a computer that has a Bluetooth 2.1 device. Is it possible to...

Doesn't that require SWO to be implemented? (Which is not on the Nordic part).
Is it true, that SWO isn't available...
In SDK 6.0 I find there is a project of ble_app_hids_keyboard_serialization.uvproj in nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard

Hey there,
today I'd tested around with the Dfu service.
Peripheral is nRF51822 running Sdk 5.2.0 bootloader example (Softdevice 6)
Central is Android 4.3 running...
I am unclear whether the soft radio takes care of updating the attribute when a write event occurs. I can see in the example codes that the notification flag is handled by...
I use a PCA10001 board as peripheral role of heart rate service and it can be discovered by control panel. But as I download the experimental program of central role of hrs...
I'm trying to understand how pstorage allocates storage.
PSTORAGE_FLASH_PAGE_SIZE is fixed, that's the actual size of a flash page and thus a basic unit as you can only...
Hi, I am trying to change the beacon data.
I changed Beacon UUID already, but I can not find where can I change device name.
I guess I need to change the gap_adv_data...
Hi,
I am upgrading to SDK 6.0.
What function should I use for retriving the whitelist data?
SDK 5.2:
//err_code = ble_bondmngr_whitelist_get(&whitelist);
