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 am trying to understand the use of multiple channels in the timer. Looks like the use of the multiple channels is for PWM/ sequencing type applications. It is not intended...
I am using nrf51822 and having some questions,as follow:
1、the pin reset is common with the pin SWDIO(the debug IO pin).when I download into nrf51822 using JLINK(setting...
I am working on a nRF52328 present in the Taiyo Yuden EYSHJNZXZ module. I am using a J-link EDU debugger to program it. Can I use the J-Link for UART communication with the...
I am developing an application in which my device will have multiple android phones connected to it. Currently I have it working with one peripheral and after having upgraded...
Dear all,
I am working on one sensor project(temp and accelerometer sensors) where our Nordic nrf51822 soc should read the data using spi protocol and transfer it to the...
Hi, im using nrf 52 DK. Im currently working on BLE UART example. I need to send int16_t data type to my smartphone's nordic uart app. But i cant. I was using the function...
Hi,
My project is reaching the stage now where we are looking at getting a contract manufacturer to start making our devices. I was wondering what Nordic suggest for programming...
First, obviously error message is not correct, dll's are not used on linux. Message should give correct file name instead of prewritten one.
I have installed latest JLink...
Hi,
I'm trying to implement a custom bootloader update on the nRF52840 using SoftDevice s140 and SDK 13.0.0. With my new bootloader staged in a scratch region of flash...
Hi,
I have copied BLE Thermostat code from ARM mbed : developer.mbed.org/.../
As this code is on mbed 2 platform, i am trying to run it on embed 5.0. Getting below error...
Hello:
I dont seem to understand what the problem is. I have 2 external ICs, one is an IMU and the other is a CDC. Both have interrupt pins connected to the nordic nRF52832...
Hi All,
I am working on a project where i need to use a SPI 128x32 OLED display and a SD card interfaced over SPI to nRF52840 along with BLE. Although, i tried this with...
