Hi all,
I want to fully understand the concept of Bluetooth protocol using nrf52811. Any advice will be helpful for me!
First, as I understand softdevice is Bluetooth...
As shown in the figure, MCUboot has a boot_go_hook function. I'd like to define this function in my own project and compile it into MCUboot. Since I'm using single slot DFU...
Hello,
We are working on establishing a connection between one of our existing Bluetooth modules (cypress) and nordic based module to provide backward compatibility with...
We are developing HW that includes nRF9151 running DECT NR+ with the Wirepas stack for mesh connectivity between multiple units. The product is expected to move between geographies...
Hi，
Platform : nrf52840, NCS 2.7.0
I would like to get the MCUBoot image swapping progress without modify the NCS, and display a progress bar on the LCD to indicate the...
We use several Nordic chips in our BLE sensors. We bond to the devices from Android, connect to update configurations, then disconnect such that the device then advertises...
Hi
I am using SDK 12.3.0 with softdevice s130 v2. When I try to combine ble_app_hrs_peripheral code with app_uart.c, uart module gives error NRF_DRV_UART_EVT_ERROR in uart_irq_handler...
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?
static uint32_t mesh_value_char_add(void)

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...
