Hi all,
What is the maximum data rate for the nRF24AP2 when using the Synchronous serial interface?
I cann't see it in the datasheet.
Is there anyone can answer me...
Hi,
In my design, there is a tag used by 24l01,It can transmit the temperature value.In the tag, the parameters are like this:

I'm having some issues getting the auto ACK to work properly. I am only receiving auto ACK messages on the first 3 received packages, after which the receiver stops replying...
Hello i have a system that build in an ultrasonic sensor RedBearLab BLE Shield ( nrf8001 ) and arduino i want to get ultrasonic data via bluetooth and see it on nRFConnect...
Hi,
My host MCU controls nRF51 over SWD interface.
How can stop/halt nRF CPU? After initialization the SWD(init/read DB/AP AHB, etc.) I need to halt (stop nRF program...
Hi,
I would like to have one page of flash mapped manually to store information critical for the device. Let's assume I do not trust data preserving by DFU or there is...
I have some BLE traffic that I have sniffed and am displaying in Wireshark. Most of the opcodes (read/write request/response indications/notifications etc.) are parsed/displayed...
I am trying to develop a GATT service on nRF51.
The GATT service measures a few values, and stores them in a characteristic. When the GATT server (phone) requests data...
I am trying to build a device to stream the 9 axis sensor data from the I2C based sensor and then transmit it using BLE UART profile. It is sampled every 3 seconds using app...
I am using an nrf51422 board. I want to update via OTA using ANT+ Dongle. The device information shown in the OTA Updater is parsed from the Bootloader Code. Is there any...
Hello!
I want to connect the MCP9808 with the nrf52832. Therefor I use i2C.
My example on the nrf52832 is the:

We're quite interested in producing an nRF52 design based on the solar beacon (great design, and clean software). I appreciate the relative simplicity and manageable BOM cost...
Hello,
I am developing a system that samples 3 independent data using SSADC. since the timing was important in my system, I decided to use PPI to trigger the SSADC.
However...
When using app_timer through scheduler, a break and go will overflow the event queue if a timer is a repeat timer. The effect is that it's not possible to debug.
To work...
