Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
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.

I have met a problem in communicating with nrf8001.
After reset nrf8001, RDYN is low which means it has something to send. Then I pull low of REQN and start receiving data...
Hi,Nordic:
I use an STM32 to communication with nRF51822 through SPI, and i set the STM32 to master,the nRF51822 to SPI slave, 51822 works as SPIS.
When STM32 send a...
Hello,
I'm working on a custom board based on nRF51822, with keil 5.12 and a segger jlink. I'm trying to setup an SPI connection with the an accelerometer, starting from...
Hi,
I have created a scan response structure containing only the BLE_ADVDATA_FULL_NAME. This is because there in no room left in the advert data to advert the full name...
