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...
(nRF51822, but also concerned with nRF52832, SD130, SDK 12.1)
I'm trying to write/erase flash from a bluetooth event handler. As it's been outlined in other questions,...
Hi,
I am just updating my application from SDK13.0.0 to SDK14.0.0.
2 Services are in use: DIS and NUS. To advertise that, I made use of the scan response functionality...
Hi,
I have the D52QD2M4IA-A chip (from dynastream) that has inside nrf52832 chip. It has also builtin an onboard LIS2DH accelerometer. However when I am trying to connect...
Hi,
I am working on nrf52832. I am preparing application where I need to handle central connection with two peripherals and keep tracking time. I know that softdevice has...
The data sheet recommends that both the TWI clock and data lines use pull ups and the GPIOs should be set to S0D1, essentially open collector drive. I can see the need for...
When trying to follow this guide for testing bluetooth mesh on a nRF51 dev-board Cmake returns this error:
../build $ cmake ..
CMake Error at CMakeLists.txt:16 (include_directories...
Hello, I have had luck in Keil making two NRF52 connect with NUS, central and peripheral. My goal is to have one central speak to multiple peripheral at same time via a piconet...
Hi
I have just baught some nRF52840 DK boards,
and I can test the BLE throught between those nRF52840 DK boards successfully.
This indeed help us a lot about research...
Hi,
I am using SDK 12.2.0 with my custom board. As per the my requirement, i need to ground or set logic 0 of my gpio pin no. 12.
So, how can i do this?
good morning to all
I wanted to ask if anyone has a design of nrf51822 where an external temperature sensor is used, to know how the connection to the chip is. Should I buy...
Hello,
I am learning about the behavior of "Notify" transmition.
From some web sites including below, I understood as follows.

So could...
Hi,
I am new to arm and ble development. I am used to work with AVR mcus and I am trying to migrate a project from AVR to nrf52.
AVR usually has some "General Purpose...
I'm transmitting data packets each of 48 bytes in the form of notifications using Bluetooth 5.0. When I observed the logs over sniffer, I see that the packets are fragmented...
Hi,
iam new to all this and hardly find answers for my question:
Is it possible to pair a nRF51422 with an Ant+ remote especially Bontrager TransmitR and use those remote...

Hi,
I am a little confused as to what component uses ble_flash (...drivers_nrf\ble_flash\ble_flash.h/c) and why? What is the difference between this and SD...
