I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.

I would like to use twenty concurrent connections. As I understand I should set ble_cfg.gap_cfg.role_count_cfg.periph_role_count = 20 and ble_cfg.conn_cfg.params.gap_conn_cfg...
Hello,
I have read with a lot of interest the documentation associated to the "multiprotocol support" associated to the nRF5 SDK for Thread v0.10.0.
As far as I understood...
This is a more specific counterpart to a question I posted on StackExchange . If you want to know more about the attack itself, check that out, but here, I'm asking for a...
Hello, please refer to the below code, in particular, did I get the cccd handle right?

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...
