Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I use ncs1.6.0 to develop on nRF52832DK. The current requirement is to enable PA LNA support on mesh.
I learned how to use FEM driver through this blog . I added the corresponding...
Hello,
Is it okay to supply the nRF21540 with a DC/DC or do I need to use an LDO? Are there any performance differences of the nRF21540 when choosing one over the other...
I'm finding that the signal strength of the radio is too low in my nRF52840 custom BLE project. I would like to increase the radio power from the default 0dB as our RSSI values...
I made a custom model under ncs1.6.0 to publish uart data. When the data I want to publish exceeds 85 bytes, an error occurs in debug:
<err> bt_conn: Unable to allocate...

Hello,
I'm using the sdk v17.0.2 with softdevice s140 with a custom PCB shipping the nrf52840.
I'm facing an issue where I cannot enable NFC and softdevice at the same...
Hello everybody. I am currently evaluating some BLE Tags, if they can be used as an BLE doorkey. The chips I am talking about are the following: nRF51802 nRF51822 nRF52832...
Hello support team,
I try to get the NRF52840 DK to work as a central with FreeRTOS. Connecting and getting notifications works well, but the device freezes on a disconnect...
I am running a Zephyr OS, and I am using the mbedtls APIs to do my cryptographic operations using the Cryptocell as my backend. My question is should I be using a mutex of...
Hello,
We have a physiological monitoring system in production where we used NRF52832 as a peripheral. Connecting this peripheral with Windows bluetooth, we realised that...
Hello,
I'm currently looking at using a last will message that updates an attribute on the cloud if the device disconnects from the broker. The broker and client agrees...
Hello everyone,
My current setup:
1.Development Kits = NRF52840
2.Nrfutil Version = 6.0.1
3.Softdevice = S140
4. Operating System = Linux
In current goal is to...
Hi There,
I am currently using a custom bootloader for my devices which was started from the secure bootloader example given in the SDK, I am using BLE as the transport...
i have nRF Connect SDK v1.6.1，excuted “west update” and “west zephyr-export” command（the project will not built successfully without executing these 2 commands）
