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'm trying to compile a simple example (light_switch__server_nrf52832_xxAA_s132_6.1.0) for Bluetooth mesh with Segger embedded studio. I'm having a hard time to get...
In nRF5_SDK_15.0.0_a53641a code, there's such definition:
#define UART_DEFAULT_CONFIG_BAUDRATE 30801920
Which means about 30.8 Mbps.
But in page 345 of nRF52832's...
Hello,
I'm using a nrf51822 board as a DFU controller to update another board's application, the client board runs the bootloader secure example. When I write data to the...
This is almost certainly a noob (to nRF52840) programming question.
I have modified the peripheral/gpiote example to invoke an ISR on the falling edge of a pin signal. In...
I am trying to use the Sparkfun nRF52832 breakout board as a master in I2C communication. I am using Arduino IDE to program the module. I defined pins 24 and 25 as SCL and...
Nordic Support, Let me first explain what I would like to achieve. I am developing a line of devices that will act as GATT peripherals. I would like average current consumption...
I have a custom board with an nRF52832 (CIAA-B0), and I am trying to use the SPI Master.
When I use SPIM1 or SPIM2, the transaction hangs, but the same code talking to SPIM0...
Dear Nordicsemi,
We are looking for Sub 1 GHz RF Module, which gives Longer Range distance in Field either in LOS or NLOS.
Please share the details regarding proven...
Hi guys,
We've written a small test on-top of our internal Bluetooth library (glorified wrapper sat on-top of SDK 15.2.0 SD140 6.1.1) on the nRF52840 to send dummy bulk...
Good morning everyone,
I am implementing a custom radio protocol on NRF52 without using the SoftDevice at the moment. For some reason, I get a HardFault which I am trying...
Hello everybody,
I can flash my custom nRF52832-based PCB using the nRF52 DK and Segger Embedded Studio or nrfjprog, but this requires that I always have my computer with...
Hi,
I need to get 1.8V on the VDD using high power mode. According to the documentation this is the default value. However, I measure 3V.
Please advise,
Daniel
I am developing a nRF-Mesh based product. This product consists of a fixed number of nodes in a Bluetooth Mesh Network. Are there possibilities to factory-provision a set...
Hi!
I am working with experimental_ble_app_eddystone in SDK 12.2.0 for nRF52.
I have seen that the firmware does not support using different advertising inteval for each...
I'm wondering whether or not nRF52840 can be used for a USB smart card development.
"According to the spec of a USB CCID device (which could be found on www.usb.org ), there...
