I successfully made an Arduino code using nordic library that gets notification from iOS ANCS.
But some minor bug exists: sometimes i don't get any notification from the device. The only thing that I can do in that situation ... (more)
i operated in the ordor below (1)i use batch file s110_nrf51822_7.0.0-3.alpha_program.bat to download softdevice 220.127.116.11 into nrf51. (2)i open ...\s110_nrf51822_7.0.0-3.alpha\Examples\DFU\bootloader.uvproj and download dfu program ... (more)
Once connected to the peer, the app will begin with "sd_ble_gap_rssi_start()", and the peer will send RSSI sample to the softdevice, and the SD will back to APP with a "BLE_GAP_EVT_RSSI_CHANGED" . Is this the right procedure to refresh the RSSI ... (more)
Hi, I downloaded the example ble_app_hrs and measured the current consumption, i found it was 1mA while advertising, this is so high. what can i do to make it possible to decrease current consumption while advertising? just like cc2540, during ... (more)
Hi, i want to use multi-role in new softdivice v7.0.0. so i tested ble_app_hrs example in sdk5.2， then i found nrf51 cannot continue to broadcast when it is in a connection. i try to start adverting when ... (more)
The err_code shows NRF_ERROR_INVALID_STATE when called sd_ble_gap_adv_start(). I want to know why it happen, and how to handle it. This happened upon the ble disconnected.
Thanks a lot.
Hi, I'm working on a Keyboard&Touchpad project, very similar configuration with Smart Remote 2, so I'm considering to use nRF24LU1+ as receiver's MCU. The receiver will be mounted in Windows PC, so it should support USB ... (more)
We have some product using nRF51r22 QFAAC0. E0 version is replacing C0 now. I just want to know when is Nordic going to stop producing the old version? Thanks
uint32_t ble_advdata_set (const ble_advdata_t *p_advdata, const ble_advdata_t *p_srdata)
If I set the second parameter p_srdata, does it mean passing encoded advertising data and scan response data to the stack together (2*31byte)? my first question is : Is the scanrsp data ... (more)
It seems that I can send 2 packets per connection interval but not more on the Nexus 4. When I try to send 4 packets per connection interval, it seems that I run out of TX buffers. But according to ... (more)
Just wondering if anyone has worked with a good BLE Python library that he can recommend. I have BLE peripherals that send out notifications. What I'd like to use the Python/Ruby libraries for is connecting to ... (more)
I'm using Nordic 8001 with Arduino.
I successfully connected to ANCS. The problem is that i need another iOS App that scans for services on my bluetooth device and after that i receive an alert to enter the ... (more)
I have a problem at restoring the bonding that is saved on Android EEPROM. I'm using Nordic 8001
I'm using the example from proximity. I modified the services.h using NRFGO to support ANCS and i added ... (more)
There is no documentation for the nRF51822-mKIT. How do I load the SoftDevice?
Can you please advice how to read "scan response" data on the central device? I'm still using 1.alpha SoftDevice.
Kind Regards, Krzysztof Rosinski
Hi all i am working on Student Response System in which there multiple Transmitter and one Receiver and i want Receiver(nRF24lu1p) to behave as HID device. Can any one provide Example code for nRF24lu1p as HID ????
Hi As far as I known, ANCS profile is for iOS7 and Alert Notification profile is for Android.
I can find ANCS example (ble_app_alert_notification) in SDK. I followed the SDK document to set up it, then open iOS7 bluetooth to ...

I am having problem with the bootloader function of s110 v7. I am able to download the s110 softdevice. My application code was recompile with v7 header files. Able to download it and run my application. So far so ... (more)
I need to write a boot loader for nRF51422. Any suggestion for it, reference site ,sample code for quick reference ?
thanks and regards Robin Singh
Hi All ,
I am trying to run the nRF51822 DFU sample code(SDK5.1) on nRF51422 new chip set(QFAAE0).but when i am running on nrf51422 i am getting below message and able to jump in bootloader but this ... (more)
hi, i survey the Bluetooth again , i have some issue about the Connectable mode
i see the peripheral connectable setting : PERIPHERAL :
Non-Connectable Mode (BLE_GAP_ADV_TYPE_ADV_NONCONN_IND) Undirected Connectable Mode(BLE_GAP_ADV_TYPE_ADV_IND) Directed Connectable Mode (BLE_GAP_ADV_TYPE_ADV_DIRECT_IND)
On the other hand , On Central ... (more)

Because I direct control the COM-Port, I do not how ... (more)
I used nRF51822, I found sometime the program reset itselft. Then I made a test program to send out the "RESET REASON"by BLE message. I found the reset reason = 0x1000C. refer to "AIRCR.SYSRESETREQ"& "CPU lock-up" detected ... (more)
I am a college engineering student working on a circuits project, and I need some help. The project is to design a proximity device that sounds an alarm when a transmitter is out of range. The device includes ... (more)
We are developing a pair of devices - one central and one peripheral at the moment and we would like to be able to read the value of RSSI on both of them on demand. The way I want to ... (more)
I have taken the S120 app, and am trying to have it connect to an external peripheral (not the provided S120 Multilink Peripheral app)
