I would like to test the newly added v4.2/v5.0 Bluetooth features (e.g. LE Secure Connections, Data Packet Length Extension, 2xSpeed, etc) against non-nordic devices. I have...
I am working on a project using a ble nano (nrf51822) using the Nordic SDK 8.1. In the examples I found a way to control an LED using the methods LEDS_ON and LEDS_OFF. I wanted...
Hello,
I am using ble_app_gls example and I have implemented static passkey in the code. Now I want to see if wireshark shows the passkey when I connect to ble devices. For...
Hi Team,
We are implementing an UART communication between a M4 processor (UART master) and a nRF51 (UART slave) and we want to use the UART in Low Power mode with flow...
Hello everybody,
for my project, i will bond the peripherial with the central.
I test my device with the MCP and can connect without problems. When i press the Bond Button...
Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...
Hi,
I'm trying to write firmware for the nrf52840 that reads from a sensor and then sends data to a PC over BLE. Ultimately, I need the BLE link to achieve ~ 1.1 Mbps throughput...
Hi all,
I observe a connection supervision timeout (HMI error code 0x08) in my Nordic firmware with certain Android smartphones (controller).
Additional info regarding...
Hi. I'm just wondering if Nordic Semi engineers have done any tests with standard beacons (any particular beacon interval and test condition) application and compared current...
Hi teams,
We made BLE mesh custom boards based on nRF52833.
These nodes are configured to send broadcast messages for every 10 seconds.
Currently, these boards uses...
Hi Sir,
We would like to use the Radio test to do the basick TX/RX test in SDK 15.2
We use the nRF52840-DK for test and follow the CLI document .
1. We use two board...

I want to know how to avoid this problem, the current transfer rate is less...
Hi
We need the recv() be blocking until the full amount of requested data can be returned or the operation was timeout, how to achieve this?
I tried flag MSG_WAITALL but...
Hi. Can anyone think of a way to use the nRF52832 (probably Timer) to detect approximately 125KHz-150KHz variable square wave down to about a 1Hz resolution? I'd like to detect...
Is there any example for Directed Advertising? I'll design my NUS central and peripheral use Directed Advertising, because I would like to have other bluetooth devices connected...
I use this code below mentioned in this question https://devzone.nordicsemi.com/f/nordic-q-a/26030/how-to-reach-nrf52840-uarte-current-supply-specification
This can reduce...
Do you have any recommendations, tutorial, blog, or getting starting guide for a developer wanting to use Mesh and BLE on the same node? Any information would help. Does one...
Hi,
After long use of BLE communication I sometimes get return code 8 from sd_ble_gatts_hvx.
My questions:
1. This return code is cryptic. Is it associated with defined...
I am trying to configure the CryptoCell on an NRF52840 to use AES-CBC encryption with PKCS7 padding. When I call the following function, it returns SASI_AES_ILLEGAL_PADDING_TYPE_ERROR...
