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 would like to have 31 bytes for my own in advertising and so far I have disabled everything except adv_flags (it still takes 3 bytes cause of length, AD type and value)...
Hi there,
just wanted to know what the practical differences between the JLINK and mbed MCU interface firmwares are.
From what I experience I can only use the UART over...
Hi,
I'm writing a service to send indications on a couple of characteristics that are part of a service. In order to determine whether indications have been enabled or not...
Hi,
Is there a smaller version of the desktop 2 firmware? I don not need firmware for NFC only ble 4.0. Also would like less complicated pairing. The 6 didgit code is unnecessary...
Hi , I tried to change the transmission power using the s110 API and tried checking if the value of the register storing the transmission power is changed or not. Following...
Hello,
I'm trying to create my own bootloader application that uses softdevice in IAR. I would like to know how to configure my project so that it writes 0x0003A000 to...
Hi all,
I've a problem using pstorage: after I execute a pstorage_clear, my ic (i have the pca10028 board) go crazy, the application I've write stop execute and I can't...
I have an application that advertises as connectable in BLE.
After connection and configuration, it should then disable connectable advertising and enable nonconnectable...
Hello,
My nRF51822 custome board has problem at first programing software with nRF51 DK. So I checked nRF51822 boot sequence and found diffence compare with nRF51422 which...
I develop my BLE with SDK 8.1 and softdevice 8.0, and I want to restore some data(about 50 bytes) to flash, can anyone please help to provide me an example for the entire...
I have had a look at you experimental implementation of DFU signing.
I'm very concerned about the code size. The old Bootloader used about 13KB and the new one with signing...
I have a custom made board that has an EFM32WG360F256 communicating to an nRF8001, verified that the ACI protocol works with repeated echos, however when I run the efm_ble_my_project_template...
I've got 4 services with 15 characteristics between them. Trying to add any more than that results in sd_ble_gatts_characteristic_add() returning NRF_ERROR_NO_MEM .
