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...
Hi,
I am running the nRF51822 from a coin-cell. I need to measure the cell voltage. Until now, I have attached VDD to an ADC pin with a voltage divider and a capacitor...
Hello~
In my production line use jig contact my PCBA, and use Jlink connect to Nordic 51822 download FW, but I found sometime can use 500kHz and sometime can't use, just...
Hi
I am using nRF52(PCA10040) as a sniffer dongle, but it seems the sniffer mode cannot work, and shows the error log: "INFO: Error on port xx. file: Packet.py, line 245...
First step of trying to integrate S132 to a small OS is failing completely.
When I use SVC the system ends up in hanging in hard fault.
The SoD handler ends up trying...
I am testing to develop an application that sleep (system-on mode) for most of the time, and it wake-up periodically to send out somethings.
As I would like to lower the...
Hello,
After when I download the protocol stack（S132）.The target is NRF52832 chip，tool is J-link OB.
I choose to recover nrf52 ，then prompt unable to fine or open the...
Hi,
In ADC, we would be using the internal voltage generator as the reference voltage. How stable is the voltage coming out of the reference generator. Would it be always...
It appears that, if I wanted to write characteristics to my BLE device, I can utilize the writeCharacteristic method of the BluetoothGatt class. Is this the right way to go...
Hello,
I am currently for a quick solution to test NRF24LE1 compliance to FCC. Can you provide me with any code if possible? As i could see from the website only an application...
Hi,
We can utilize the 31 bytes of advertising packet as well as 31 bytes of scan response packet which in total makes it 62 bytes of advertising data. What is the effect...
Hi dear Nordic Engineers.
We going to move from FN-LINK (Realtek) I.C. BLE to nRF52.
FN-LINK uses HCI (UART) BLE the Interface to communicate with our embd. LINUX.
How...
Hi all,
I'm using pca10040 board with sdk version nRF5_SDK_11.0.0-2.alpha_bc3f6a0.
There i'm using example code of spi handling. Instead of nrf_log_printf i changed...
Hello,
There's any known issue realated with DFU and Android 7.0? When we try to update firmware with nRF Connect or our APP we get an error (hex file error), but when...
I am going to develop an application on nfr51422 that requires very low current consumption. Basically we plan to make the nfr51 to "sleep", and it will wake up constantly...
