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 use a smart beacon kit (rev 1.0.0) and I would like to know how long the cpu is blocked during the data transmission/reception. I set the connection interval to 10ms...
We are designing a nRF52 based circuitry based on "53.2 Schematic QFAA QFN48 with DC/DC regulator setup"
In the reference diagram, there is an Optional block for the LFXO...
Hey all,
I've created HIDs using USB before which require a vendor ID (VID) and product ID (PID). Are these necessary when creating a device that uses HID over BTLE? If...
Is it possible for nRF52832 to drive an SPI TFT 240x240 LCD and a TWI Capacitive Touch Panel with BLE and NFC? Is 64Mhz the highest speed?
What I mean is that is it possible...
I am creating a project which must use two spi at the same time , the one store data to flash and the other use to communicate with FT221 .In the datasheet ,I realize that...
Hi Devzone,
We are currently awaiting arrival of our custom board, based on the nrf52 chipset, and I've been tasked with determining any potential gotchas with programming...
Hello,
I am trying to implement a star network with more than one datapipes enabled, where (between other tasks) the PTXs devices have to synchronize their clocks (real...
Hey, I am compiling some code to both read ADC measurements and send the measure it over UART. I looked at the ADC+UART+SOFTDEVICE example on github and I think I am pretty...
Can you please provide me the iROM and iRAM settings for the S110 softdevice for the nRF51822? Specify the SD version you are using please.
I'm reading nRF51822_Development_Kit_User_Guide_v1...
hi
i get vlaue with this line of code
but i did not specify what char should get it value
how can i get value from specific char?
i have nrf51422 v2 sdk v6
hi,
Everyone,
I was just checking on nrf51422 Dev kit for LFCLK and HFCLK oscillator configuration.
with lfclk set to start external oscillator ,it does not start external...
I have a Project using DFULibrary framework in my workspace. When I try to archive my target to generate the IPA file, the IPA file is not generated and can't be exported...
hi,
when i run the application , i used the external spi flash to download the firmware from my company's server, then make a upgrade flag to the spi flash and reset the...
