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.

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...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hi,
I was wondering if anyone could clarify why there are enable, set and clear (CHEN, CHENSET, CHENCLR) for the PPI channels when according to the data sheet they all...
I checked S130 document for using nRF51822.
I want to change the nRF51822 like the following mode.
peripheral => central => scanning => peripheral => central => scanning...
Hello
I am trying to change the ticks value of Battery measurement interval (ble_app-prox example) but i am not able to understand how the ticks period is measured based...
Hi,

The address miss event is not shown as a transition in Figure 22 of the NRF51 Reference Manual. What state does the NRF51 enter upon an address miss and how long after the...
To use BEL application, the soft device must be downloaded before programming.
i can find a table shows that which soft device version is suitable for chip version.
how...
Our application is developing RC units for small (indoor) model airplanes - we want to be able to have multiple planes flying at once without "stepping" on each other.

I'm developing a NUS-based peripheral and adding a timeout to force a disconnect after a period of inactivity (i.e. no incoming NUS data). However my peripheral also provides...
Hi all,
I'm trying to use Ant+ HRM RX demo profile from nRF51_SDK_10 ( nRF51422 ) between my board PCA10028 and a Garmin rate sensor but I get some trouble.
Let me explain...
In the example iOS app and the DFU service in the firmware there is a DFU revision characteristic UUID 0x1534. The Nordic SDK documentation don't mention this characteristic...
HI，I'm having trouble in flash operation.I I did an experiment of flash operation.I call pstorage_store( ) or pstorage_load( ) very second after nrf51822 connected with app...
I would like to know how long TXIDLE state takes, between sending two data packets, for NRF51822? I want to minimize the time between sending two data packets, to maximize...
Hi,
Everyone,
I am trying to understand BLE app code and using debugger to find the values of the data sent over BLE during advertising mode.
But during debugging I...
Hello,
I am designing a custom protocol using the radio as a peripheral. The protocol has the chance for two nodes to transmit at the same time on the same channel. My...
