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...
Hi,
I am currently trying to use PCA10001 board as master and slave at the same time. Trying to send data from master(SPI0) and receive it using slave (SPIS1).
I have set...
Hi,
Is exist a tool like nRFutil to make DFU from windows with standard BLE ?
I have found this: https://github.com/NordicSemiconductor/pc-ble-driver but I thing it's...
I'm trying to filter devices by first provisioning a device then checking the composition data for vendor ID,etc... It is a real pain that all that data is only available...
Hi folks, I am trying to talk to the nRF241L from a PIC 16F688. It is my first time with SPI, and to complicate matters I code in assembly only so cannot refer to online examples...
Hi,
We are trying to have control on firmware update of our BLE mesh network. As a starting point I have ran the light-switch examples and DFU over mesh example. In light...
We are develop one product, it is power by four AA battery. It works fine. but now I found a problem. when I power off and then power on again, sometime it can not be reset...
when I start ADC the current will be HIGH .even I UN-Initialization it .
what I have done like that below;
before I started it The current is 0.6ma
but when I start...
I'm trying to communicate with a device over UART, and I'd like to return the response to my commands back to the function the transmission came from.
For example, I want...
I want to develop nrf52840 with ble mesh topology.
However I need one node to transmit data received from all the nodes via uart to a gsm module
Can anyone please tell...
Hello Nordic experts,
I am trying to use app_usbd_ep_enable and app_usbd_ep_disable in order to enable/disable an endpoint. I need this to fake usb unplug/re-plug. Currently...
Hello. I am testing the sending and receiving of UART using nRF 52840-DK. If you change the UART pin settings as follows, you can receive but you can not send. It is confirmed...
Although I have already seen this discussion ( https://devzone.nordicsemi.com/f/nordic-q-a/35183/no-idea-how-to-get-manufacturer-specific-data-in-central-side-from-advertising...
Hello,
I have an nRF52840 chip ( Holyiot nRF52840 module ) and I want to program the chip using an nRF52840 DK. The Holyiot module is basically an nRF52840 mounted on a...
