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 want to develop one FOB key which will be in TX mode only to transmit a key continuously or at specified interval at ultra low power mode and powered by CR2032 coin...
I'm having really terrible RF performance with a PCB I've designed using a nRF51822 QFAC, Johanson 2450BM14E0003 balun, and a PCB IFA (from TI DN0007: www.ti.com/.../swru120b...
I would like to create a large “virtual” read only characteristic that does not fully exist in memory. I understand that large characteristics are transferred in chunks of...
I am trying to enable a critical section in handler. I need to update a sensitive global variable when a button event occurs, and the fact to enable/disable the interrupt...
I have nrf51822 and I use latest SD130. I scan nearby ble devices. In my case they are iPhones. When one device is in rage then I connect to it and start scan again and keep...
Hello to everyone!
So, now I try to enable a DFU for nrf51822 (S110 7.3.0)and have some problems with it.
I can't find a good example project including DFU, all that I...
I've created a simple test to demonstrate pstorage store/load for 64 pages of 1024 bytes each. To allow 64 flash pages I set PSTORAGE_MAX_APPLICATIONS to 64. Each page stores...
I've been following the custom service nAN-36 instructions and have it mostly working on my PCA10028 board, but I have two problems that I just can't figure out. I'm pretty...
I used to be able to see my development kit in nRFgo studio and flashed S110 onto the chip. Now all I see is: "No boards connected". I am still able to flash programs onto...
Hi,
We've been seeing an intermittent connectivity issue in Yosemite in discovering BLE services, namely scanForPeripheralsWithServices does not return anything. The same...
I have based my project on the SDK 6.1 ble_app_hrs. In main.c is included app_gpiote.h which I assume is for the app_button module. However in a separate class I also use...
I'm currently using soft device 110 version 7.1 on a 51822.
I have several characteristics that are more than 20 bytes that as a server I want a client to write to. I actually...
Hi, I'm using the GPIOTE library to detect an interrupt from a sensor, query the sensor and update the gatts value. The problem I've found is that the IRQ priority is hardcoded...
Hello Sir or Madam
Now i am using NRF51822 of your company. Now we are evaltion thermal character of this component.
So please kindly provide theta JC (junction to case...
