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...
Hello All,
I am working on the NRF51822 custom board.
I am Using the SDK 12.3 with s130 (PCA10028)
1.) Is it right sdk for nrf51822..?
2.) Facing issue in configuration...
Hello,
I am working on a beaconing application and I was wondering if it is possible to run the code beginning with system off mode and wake up the board with a button press...
Hi,
we are using a sensor which streams out buffered data to an ios or android app. If we face a disconnection the data gets buffered and send when reconnected.
But the...
Hi,
I am using customized nrf52 board with softdevice s132
I am trying to interface External Flash (MX25L64) using spi.so when ever i am trying to send any command /data...
Hi
I figured out, that the macros in nrf_esb_resources.h are wrong.
You can find the used resources (PPI, TIMER and SWI) of the ESB library in Enhanced ShockBurst...
What is the operating and storage temperature range of nRF52840-DK development kit and USB dongle? We need to use these evaluation boards at a temperature range of -20 to...
Experts,
I'm trying to use NRF52480 Dongle to communicate over UART serial port. On the forum I found that pins 1.10 & 1.13 are used for TX/RX. I learned that flow control...
If i buy a raw nRF52832 chip and design the circuit by myself, how can i pre-programm the serial bootloader in it? So i could use the FTDI Basic (or an FTDI Basic -like device...
Hi,
Is there any way to change the advertisement name before switching to DFU mode?
I have a custom app that reboots into DFU mode (via NRF_POWER -> GPREGRET ). I want...
Hi,
I've to design an alimentation with capacitors to keep energy and filter current peak. To do that I need to know timing for NFC peak current. Do someone have information...
Hello,
I have a running system constituted of a central and 15 peripherals using nRF52840 devices. The central is set to scan the peripherals for 5 seconds then stop and...
Hello,
I'm implementing a beacon scanner with nRF52 using nrf_ble_scan.c. After the scan has been configured with no filters, no advertisement reports are returned to the...
Hi,
The definition of the COEX1 pin looks to be really interesting for applications that need a reliable time reference. A 1PPS GPS output is very useful; absolute accuracy...
Hi
Our nRF9160DK card seems to have stopped working. We attached a sensor to the card (We might have connected the reset pin on the P7 strip) and now I can't start any program...
I was trying to make sense of the serial support in mcuboot, but it uses a protocol and format I don't recognize. I expect they're generated by the Apache Newt tools, since...
