Hi,
How to work with the connectable directed advertisement (BLE_GAP_ADV_TYPE_ADV_DIRECT_IND) event?
I modified the ble_app_template application to support direct advertisement...
Hi,
I am developing a test board with a nRF51822 and ST balun (NRF01D3) and a chip antenna (probably Johanson 2450AT18A100 or B100). The board will have 4-layers. The inner...
nrfgostudio_win-32_1.15.1 program softdevice s110_nrf51822_6.0.0_softdevice.hex works well with STlink for nrf51822 but when I program bootloard error appear :

Hi,
I'm using the redbearlab shield in combination with an arduino uno r3.
I want to send sensor data at about 10 hz to my smartphone.
This works but sometimes I get...
Hi Team,
To implement iBeacon what are the things to be take care at the peripheral side.
Whether the code for advertising the peripheral in "CoreBluetooth" and "CoreLocation...
Hello,
I am trying to get the PCA10001 evaluation board going with BLE, and am trying the ble_app_hrs example from the SDK as a start. I am developing on Mac OS with Eclipse...
Im trying to have the s120 modify the value like I would in Do a Read all records operation in the Glucose example. I cannot figure out what function would enable me to do...
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...
