I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
I am working with the nRF8001, and I'd like to create a services.h file that will let me broadcast battery level and as well as allow temperature to be read by a peer.

Hi We have an application where we what to read i2c sensor data over the air to an iPhone. We've taken ble_app_uart_S130 project and grafted in some twi_hardware code. There...
I am interested in the S130 ability to hold 3 central -> peripheral links over BLE, and am looking for some evidence that this has been accomplished with extremely low-power...
The SDK function sd_ble_uuid_vs_add may return NRF_ERROR_INVALID_ADDR If p_vs_uuid or p_uuid_type is NULL or invalid.
When the pointer is not NULL, how does this function...
Hi, I have both the nRF8001 dev kit and the nRF51822 Eval Kit (EK). We are using the nRF8001 for most of our project with the BLE Arduino SDK. But I wanted to just load a...
Hi we are using NRF51822 board.
i flash ble_app_hrs application. then it is giving advertisement.
but when i call twi_master_init() function from main. advertisement...

Blicky project runs and I can set break points and run through them - watching the LEDs blink appropriately. However, the HRS and Proximity projects will successfully load...
Hi all,
I'm using the LE1 to do the mutilceiver,if I donn't use the dynamic payload,I can do it successfully.However,if I use the dynamic payload to do Multiceiver,the...
Hi,
For the LE1,I found that 32.768kHz crystal oscillator need long time(about 350ms) to running,I must do some delay(about 350ms) for the software then use the RTC,or...
In moving to the "rev-2 51422 silicon, we find that the app_timer inevitably fails after minutes to several hours. Power requirement moves from about .002ma to 4.5ma then...
Hi,
I am planning to use an external DCDC to supply the NRF51822 in Low Voltage Mode.
In the datasheet a voltage range of 1.75-1.95 on VDD and VDD1.8 is mentioned. ...
Dear all
I'm testing for RF stability. As i used 24LU1(host) with 51822(device) be the platform. For audio data transmission. 8k 8bits data rate.

Hi,
I don't have any problems running the bootloader with S110 7.0.0.-3.alpha on the PCA1001 but when using the same code (minus the led and button config of the PCA1001...
Hi,
I am having a hard time with the permanent storage.
I got it to work with updating a 24 bytes long struct in a persistant block of 32 bytes.
I noticed that the...
Hi,
What is the suggested method to change a pending request, and make it earlier than previously requested, without closing and reopening the session?
For example,...
Hello Gentlemen,
I'm looking for a good example on how to pair BLE sensor and Android using static passkey. I looked at ble_app_gls but I could not see how they set the...
