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...

In order to prevent communication from middle-man attack, I append the signature after ECDH publickey. However, though I get the correct share secret by ECDH, I fail in verifying...
Hi,
I'm using the bluetooth 5.0 and base on the mutilink_center example to add a peripheral and a center. Because I want the center to connect two type device. It could...
Hello,
I have two identical devices with Laird's BL600 chip (that uses NRF51822). They are initialized as NRF_GZLL_MODE_DEVICE and use GZP library (without encryption ...
Hi,
I am trying to write my own bootloader. I gather new image via serial and store it in flash in my application at 0x30000 then invoke reset and in bootloader I want...
Hi,
I was testing the pwr_mgmt project in the nRF5_SDK_13.0.0 with my 52DK, the system off mode seems work fine ,cause the log information is right,but the question is...
Hi,
We are working with NRF 51822 in a multi-role arrangement (SDK 12.3.0, s130_nrf51_2.0.1_softdevice) where one NRF51 will be connected to a phone in peripheral mode and...
when i use pc tools or APP except "nRF Connect" to connect my 51822,i can not find some parameter,so i want to know in example "ble_app_uart",how to set up connect parameter...
So apparently, for ble, all CCCDs, regardless of what the UUID of a characteristic is, is
00002902-0000-1000-8000-00805f9b34fb
And to access that, the proper step...
