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...
Exactly what baluns are known to work with the nRF51822. I believe there is the STMicro balun and am uncertain about the status of the Johansen balun. Is there a list of preferred...
Hi,
We are using nRF51422 in our project and we observe a strange thing, that even there is no external pull up resistors, the I2C communication using the built-in TWI...
Hi,
I am trying to power off and/or disable a RR[0] with no success.
I am Powering OFF the watchdog in main and then successfully POWERing ON in wdt_init but then I...
Hi,
I am trying to create a star network with 12-16 slaves and one master.
The master would be a nrf51822 and the slaves nRF8001/2.
The slaves would not transmit...
Hi,
I'm using the UART_OVER_BTLE base example and I'm investigating what needs to be done to enable security.
Using the Following security configuration the device stops...
Can you tell me which antennaes i can connect with nRF 8001 to make it discoverable and transfer data. And i think pi network is solved depending on the antennae only. Can...
Hi,
Is it possible to extend the RAM memory by using internal flash memory?
Actually i need to collect 4KB of data from accelerometer and flash it to the EEPROM when there...
I'm working on a device which may spend months, or even years as deep as 1000 ft underwater...a harsh environment. Accordingly, the PCB will be completely encased in plastic...
Is it possible when using the S110 softdevice to limit the maximum number of packets per connection event? I would like to reduce the maximum amount of time the CPU spends...
The 10000 dongle does get detected in nrfgo Studio but the 10001 board does not. There are no USB devices with exclamation marks or otherwise undetected when the 10001 is...
Hey folks,
I am currently trying to expose a local name for my nrf51822 chip but whenever i change it from NO_NAME to any of the other options and run the program it doesn...
I am using nRF51422 Evaluation Kit with the latest silicon revision which comes with programmable softdevice. The kit also contains an ANT USB-m dongle. I have followed the...
Hi,
I need the 16 bit timer1 to have high priority, how do i set this to a high priority? And what priority does it have in my case when i use:
NVIC_EnableIRQ(TIMER1_IRQn...
Hello
I have a nRF51822-EK evaluation kit, I have succesffuly installed the nRFgo studio and Seggger software so that I can detect the dongle and it shows up on device...
