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
We have custom nrf51822 board.
in that we have nor flash which is spi compatible.
so in order to read device id i used spi_master sample source code.
i am able...
Hello,
I'll explain my code:
NRF51 takes samples of a sensor every 10 minutes. In addition, softdevice S110 is used... An user can connect at any time, so advertising...
I am trying to implement frequency counting on nRF51822 by counting number of pulses in a given period. I create a PPI channel with a GPIOTE event on rising edge linked to...
Hi,
is it possible to mount a nRF51822 in an aluminum enclosure and use ble?
I am looking for a range of up to ten meters in an open area.
Is that possible or will the...
there is no bin folder under C:\Program Files (x86)\Nordic Semiconductor\nrf51 as described in the docs.
so I'm not sure where the nrfjprog.exe should be
I am trying to better understand how the nRF51422 handles sqrt(n) coming from C in Keil?
Can anyone explain, or link to resources which do? I am having difficulty finding...
Hi all,
It is possible to install and develop projects using 2 SDK versions simultaneously?
nrf51 SDK will be used in the current project and nrf52 SDK will be used for...
I want to do 2 things with the nRF51822 beacons
Add an ADC output to the advertising packet (non-connectable mode)
Set the advertising interval to 1 hour or longer...
I measured the current drawn by the nRF51822 beacon with its default beacon code. The current was about 1 mA which was same as in another thread
The suggested solution...
We have been manufacturing for a while with the nRF51822, Revision 2, and WLCSP package and build code D0 (D0 is what Nordic recommended me to spec to contract manufacturers...
Hi all,
I have application that read analog level and send the data with connection interval of 10 ms and 0 dBm, how can i calculate the current consumption of BLE? i read...
Hi
I want to use Printf() in the DT2 but it cannot output msg to terminal.
I used hal_uart_config() to config UART TX/RX/Baudrate... in mail.c then
call hal_uart_put_str...
I use S110 V7.1.0,nrf51822 chip,
now I need write and read flash data in BLE mode.
When can I write the flash data at BLE mode?
When can I read the flash data at BLE...
I'm calling the requestData function and lib_aci_close_remote_pipe at the same time.
The lib_aci_close_remote_pipe returns 0x8E command error which means: "Command rejected...
