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.

Hello,
Connection between linux router and NRf51 devices worked before I've updated kernel version from 4.09 to 4.3.
Now, with the same configuration and hardware, I'm not...
I am trying develop a project in which when we request a characteristic from phone( read request), we will read data from other module through UART and give reply back. I...
Hi,
I designed before my board for 2 layer PCB and i used the coplanar waveguide with ground-plane in the bottom. now i want to move to the 4 PCB layer and i choose the...
Hi, I'm porting my project from SDK8.1 to SDK10.
I replace static app_timer_id_t m_beacon_timer_id; to APP_TIMER_DEF(m_beacon_timer_id);
to avoid hardfault when creat...
Hi all:
I modified DFU-BLE to make it suitable for S130 on nRF51822. I made the following modifications:
On "dfu-ctr1_pt_add"
ble_gatts_attr_md_t cccd_md;
memset...
Hello!
Until now I am using a nRF24L01 with johanson balun (2450BM14A0002) and MIFA.
I want to add a power amplifier to my nRF24L01 project. Can anyone give me advice which...
Hi
I have a programming issue with nRF51822. I am using the nrfjprog.dll to program this microcontroller in my test equipment via J-link Plus. When I have programmed a...
I am using single NRF24LU1P-F32Q32-T ic.i am using it only as a TAG transponder card .i wanted to know that can we program it to transmit only if there is no other controller...
hello everybody,
I measured the current consumption in two cases : in the advertising mode the current is around 4 ~ 5uA, & in the connected mode, the current is 160 uA...
Hi,
I am new to forum and to Ble. sorry about my week English.
I am working on a project where I am reading adc value every 1s and sending it over ble. So I have written...
Hi,
I'm using nRF dev kit with Softdevice 1.0.0.3.alpha. The device shows advertising state at LED1 as it should, however i can't detect "Nordic_UART" via nRF Master Control...
Is the advertising interval between two packets P1 and P2 defined as:
Interval = P2_start - P1_stop (time between packets)
or
Interval = P2_start - P1_start (time...
In a project I worked on using softdevice s110 v. 7.1.0, if the receiver hadn't enabled notifications, sd_ble_gatts_hvx would return an error, so I used the following construct...
