I'm using the nRF52840 and Gazell Pairing (GZP) to develop a device network. Because I need bi-directional communication, I am not using GZP's encryption feature, as it does not support host-to-device communication when encryption is enabled. When encryption…

Hello, I am trying to develop a 1000 Hz wireless gaming mouse. The mouse has a NRF52832 onboard and the dongle has a NRF52820 on it. (Cannot switch to 52840) I do know about Bluetooth LLPM, but I'm trying to avoid it since it is expensive in terms of…

Hi, I recently purchased an nRF52833DK and tested the attached code. When using Gazell, the maximum throughput I achieved was around 85,333 bps. However, according to the explanation in the following link: https://devzone.nordicsemi.com/f/nordic-q-a…

Hello! What are the steps I need to take to switch from BLE protocol to lets say the Gazelle protocol? Is it as simple as disabling the Softdevice? If such a function exists- will it take care of resetting interrupts, freeing resources etc.? This is how…

Hi, I am working on a project where I have two separate physical devices , each based on an nRF52832 : One device is a BLE Mouse The other is a BLE Keyboard My goal is to make both devices appear as a single HID device when connected to a…

Hello! I am trying to get gazell to work on the nrf52840 dongle. I built the nrf connect sdk Blinky project with the nrf52840 dongle set as the config. then pushed the merged hex file to the board using the nrf desktop programmer- it worked just fine…

When I recently tried to write a Gazell project using the nRF Connect SDK, I found that many files referenced the `nrf_gzll.h` file, but I did not find it in the nRF Connect SDK directory. Can you tell me where it is or how it was created? For example…

I am using nRF52833 / NCS 2.8.0. I'm using Gazell Pairing, but I only need pairing, not encryption. So I'm only using unencrypted pipes. If it is a non-encrypted pipe, it is possible to use ACKs from the host to the device. Past Q&As have shown that…

I am developing a USB dongle (nRF52833) for computers and a controller (nRF52833). As a basic configuration, multiple controllers need to be connected to one dongle. Multiple controllers will send data to the dongle at the same time. Is there a good…

Hi, I'm working on a project where I want two units to be able to wirelessly send packets to each other whenever they need to. Sometimes only one of the two units may be sending packets. Looking at the documentation for bidirectional communication…

I am an embedded software engineer and have experience developing BLE devices with nRF5SDK, but this is my first time using Zephyr/NCS. I am developing a USB dongle (nRF52840) for computers and a controller (nRF52840). As a basic configuration,…

I'm going to add frequency hopping to ESB so i have some problem 1、Whether demo is available for learning. 2、for example Gazell frequency hopping ,Where can I see detailed code design instructions. Looking forward to your reply！ Thanks a lot…

Hi all, I have an application that is pretty simple. One master that needs to stream small payloads (sub 32 byte) to a receiving device. The payload is a fixed size and all I care about is achieving the maximum polling rate/update rate possible. I…

Hello, This is my first time taking a crack at embedded wifi, and I'm currently creating multiple wireless devices to pair with a usb dongle. The Antenna prototype is being sorted in Matlab to get a tuned footprint that—hopefully—fit the enclosures…

I am currently testing the sample gzll_ack_payload_device and gzll_ack_payload_host code for the Gazell protocol. I am building my project using the nRF Connect SDK extension in Visual Studio Code on a Windows machine. I am using a custom board based…

I'm considering various protocols for mobile robotics applications using Nordic nRF52-based transceivers. The Gazell protocol looks to have a number of appealing features (data rates, channel hopping, packet resend), but it seems specifically designed…

Hello, there is A problem in the process of routing communication with 51802. The implementation flow of our routing communication is as follows: application layer message flow: A->B->C, and then C->B->A. This communication is completed. In this process…

When using a third party pre-approved module, does using my own custom firmware invalidate the modular approval status of the module? More specifically I would like to use a certain pre-approved nRF52805 module, but it comes preloaded with BLE firmware…

Hello I am using the nRF7002-dk board for my project. The main goal is to be able to use Wi-Fi and also a 2.4GHz proprietary protocol for low latency communication between devices. In the case of having two wireless protocols simultaneously I found…

Hello, I am learning the development of Gazell Link Layer. https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/gzll/doc/api.html#c.NRF_GZLL_CONST_MAX_PAYLOAD_LENGTH This macro is written in the document, and I checked that its…

Hello, I'm working up an application that uses BLE and Gazella with a 'base' device that typically operates as a gazelle host to communicate to devices and then at the push of a button switches the gazella off and starts up BLE advertising to communicate…

I try to use Gazell and USB HID to remote wake up my computer. But after compter turns into sleep, the callback function on the Gazell Host Device doesn't being called back anymore. The callback function will start work again after I wake my computer…

Hello! We are developing with nRF5 SDK 16 on a nRF52840 - is there a certain cause that connection settings for e.g. Gazell is stored in NVM mode? We were concerned about flash wear and rewrote the gazell pairing library to use FDS, also beeing able…

Hello Nordic Devzone Community, I am currently designing a remote control system for an Agricultural Unmanned Ground Vehicle (UGV), and have some specific technical inquiries that I hope to get your insights on. Our system has several high-level requirements…

We've been using nRF51822-QFAB-C0 for a few years without any problems. It is being used for rf comms with Gazell (S110 8.0.0 and SDK10.0.0) If the software is put in the QFAB-A0 it appears to run until a transmit occurs in Gazelle. The timer interrupt…
