Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
I'm trying to enable the S140 softdevice on my nrf52840-PDK from NuttX. When I call sd_softdevice_enable(), it returns NRF_ERROR_INVALID_FLAGS, which is not one of the documented...
I hope, operating BLE 5.0 at low data rate will give us longer range in open space. So in an environment like a football field, where each player will have 5.0 operating devices...
Hello,
I tried to add the code of the bluetooth tutorial called "Bluetooth low energy Characteristics, a beginner's tutorial", with a code that measures the delay of two...
Hi
I am working on a design using an nRF24L01+ in a circuit also consisting of an ATMEGA microcontroller and a H-bridge motor driver driving a brushed DC motor. The whole...
hi all!
I would like to ask the DCDC and LDO two modes of choice. My product is a watch, it uses the cr2032 battery dropped to 2.5v by an external LDO to 52832 power supply...
Hi,
I am using nRF52832 development kit PCA10040 V1.2.1 2017:38. I am able to successfully run nRF_Examples\nRF5_SDK_14.2.0_17b948a\nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral...
hi,

Is not...
I'm trying to configure UART functionality in my program, and in the event handler under APP_UART_DATA_READY I'm missing bytes that I should normally have received. The code...
Hi,
Is possible to program the nRF52832 with a target voltage between 1.7V to 3.3V? I'm thinking to power supply the MCU with a pair of AA batteries in series.
Thanks...
I am using the "Nordic Uart Service", example to create a simple serial console which allows a user to change settings such as tx power, advertising intervals so that different...
As in the circuit diagram attached where the pin resource is insufficient For one Pin (AMULTI), I design gpio for Button and analog input as 2channel. (This switch uses the...
