After implementing a throughput test for BLE using #nrf52840 hardware and Zephyr 1.14-rc1, notice some curious behavior in data we are collecting. The test seems to show that sending data from the cen

Hi Henry, Take a look at the configuration used in Nordic’s throughput sample: https://github.com/tejlmand/fw-nrfconnect-nrf/blob/master/samples/bluetooth/throughput/prj.conf I think you are missing s

I am trying to enable data length extensions in a connection but am limited to the std 20 payload bytes. I have a Nordic PCA10040 (nRF52832) running Zephyr v1.14rc1 as a central connected to a Laird B

Hi Josef, There is no maximum, neither as a central nor as a peripheral, nor combined. Whatever you can fit in RAM and in multiplexed time (depending on connection intervals, use of slave latency, etc

Hi, I am evaluating the use of nRF52 (HCI with BlueZ/Linux) as BLE central device. Does anyone know the maximum number of concurrent connections which Zephyr supports? Many thanks, Jos

Hi guys, I'd like to encrypt the advertise packet since some secure fields in the payload. But I did not find any clue yet. So anybody knows how to implement this feature with zephyr? Thank a lot if y

Hi, I am making a program in a slave (peripheral) device. I can get a master (central) device connect to the slave (peripheral) device. But, how can I make the slave device to get the device name of t

Hi all, I'm developing a system with Zephyr that has been configured to have 4 Bluetooth connections and 4 paired devices for a Nordic nRF52832 SoC. CONFIG_BT_MAX_CONN=4 CONFIG_BT_MAX_PAIRED=4 I'm fin

Hi. It looks that you have HFCLK running all the time. This is probably caused by small issue in power management code. Please try to remove the calls to nrf_power_task_trigger() from soc/arm/nordic_n

Hello, In order to use the peripheral and central device for energy efficient application, I performed some power measurement test with the following configuration using nrf52 DK. Central_hr sample ap

Hi Robert, Can you please open a GitHub issue and assign it to @jhedberg ? Thanks, Carles

Hi, When could we expect that blemesh code will be usable in c++. Most header files in zephyr are compatible with c++ but not ble mesh headers. No #ifdef __cplusplus in headers. Regards, Robert

Your config file looks ok. I will check if errata 201 will solve your issues. I will try to send you a patch by this weekend. As I will need to reproduce the issue, you will need to help me if it is t

Hi Vinayak, I did some test today by using the latest master, there is no connection parameter update that means the CI keeps in 7.5ms, the connection keeps alive. I try to update the CI to 30ms manua
