Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
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...
Hello,
I would like to build a tool in Python that allows sniffing/interaction with BLE traffic between nRFgo modules (nRF51822) and a Mac via the master emulator. I am...
I have bought the Bluetooth low energy evaluation kit nRF51822. It can be paired with a Nexus and a Sony Xperia without problems, but it does not appear at all on Samsung...
L.S.
Today I decided to have a look at SDK5.1.0 for nRF51822 which supports the S120.
It is deliverd as an msi file with (as far as I have noticed) no support for specifying...
Is there anything preventing anyone from uploading the tinyest image that simply dumps the entire ROM content on the UART?
This would sort of circumvent the HW locking...
Hello,
I use nRF51822 for my project and I would like to purchase some BLE packet sniffer. Does anyone recommend any sniffer? My purpose for that is debugging and check transaction...
On PCB layouts I often see that the HF xtal is oriented at 45 degrees relative to the orientation of the 51x chip (that is to say the edges of the the xtal and 51x chips are...
Hello Nordic expert,
Regarding the antenna load impedance, I can find the data in nRF24L01+ datasheet and it is 15ohm +j88ohm.
But I can not find the antenna load impedance...
hi,

Since I'm writing code for my own board, I decided to create my own board.h file to hold the board-specific definitions.
However, I can't do this without hacking the SDK...
Hi,
We have two services, apple ANCS and Alert Notification on iOS. We try to connect it with 51822. There is an exception case the the alert notification function not...
Hi,
Sorry, it looks like a ios question. We found that when connected ~10 or more 51822 devices, the iOS BLE will malfunction. We can no longer connect new device to the...
Hello,
I'm using the nRF8001, and I'm trying to max out the bandwidth between itself and an iPhone. The iPhone's connection interval is 30ms (minimum). I'm sending 20 bytes...
