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 have recently started using the new rev 3 parts with 32K of SRAM and I was wondering what the timeframe is for the softdevice to take advantage of the extra memory?
My...
I would like to understand when I would need a wired programming (with help of TC2030 connector) interface and when I would need OTA. I am trying to find the easiest and fastest...
Hi,
What is the difference between using WFE and sd_app_evt_wait to force the processor into sleep mode?
We're trying to optimize for power consumption, and somehow...
I have experimengted with prepared write on Nordic 130 softdevice and found it's quite
low performance in terms of throughput.
First, between iOS/Android device and Nordib...
Hi Nordic's experts
We got a RF problem in certification test, attached picture is the measured occupied bandwidth, the value of OBW is 1.73MHz , but the guy in the lab...
Hi,
Does anyone known what the maximum frequency is that the timers can operate on ?
I want to count a signal that is 24Mhz while the clock frequency is only 16Mhz.
So...
Hi :)
In my program, just ONE pipe to use advertising service data is not enough. There is the function:
lib_aci_open_adv_pipes(const uint8_t * const adv_service_data_pipes...
Hello,
Sorry for this newbie questions.
I have a side project (connected device) that will need a BLE component for communicating with phone apps (android, iphone). I...
Hello, everyone
I am trying to let our nrf51822 board transmit data automatically after the cccd modification. I have been use the Master Control Panel to do this. For example...
I'm using the PSA1001 eval board with SD 110. The device comes up advertising, I can connect and access my services. I need to the Central to be able to issue a disconnect...
Hi.
We are doing a few test on the S120 range with the Softdevice v1.0.0. We have a peripheral device that we can scan and connect it with iphone within 50-60m. However...
While scanning for advertising beacons with startLeScan method, this method also request peripheral device for scan response and stores it in scanRecord. I only want to scan...
Hello,
i'm sorry for asking again, but i read nearly all threads about I2C and didn't get any answer yet.
I want to use the interrupt to control the I2C sequences and...
According to the data sheet for the nRF51822 the channel range is from 2.400 - 2.483 GHz.
In the radio test example however, it limits the range of test channels to 2.400...
