In the nrf51 series reference manual section 12.1.9 it states that there is hardware protection that prevents write instructions from being executed and that there is more...
Hello, I have established the connection between two pca10001 boards, one as central and one as peripheral using multilink_central and multilink_peripheral. I have serial...
Hi,my friend,
Now,I use nrf905.Situation is as follows:
I use the NRF PCB circuit of data manual.Nrf905 work, often loss of data.
1.The Product host is to use the stick...
Hi,
I want to use the Blend Micro with more security. I want use a passkey for the Bluetooth connection. For example through the iOS Device.
Is it possible? Static passkey...
How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
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 there!
i'm struggling with the problem about using i2c with IoT SDK.
my project is about transferring sensor data (i2c) through ipv6 over ble , so i used the IoT softdevice...
I'm considering purchasing a nrf51 sniffer USB dongle. I believe I can use this to sniff beacon packets and with wireshark view the packet internals, data, channel number...
Hi
I tried to flash the softdevice with nrfprog, but it does not work. Even with nRFgoStudio it does not work.But with IAR I can program an example of the SDK (without...
Hello, all
I have a problem with ble data exchanging.
I have programmed an application which controls servo motors through phone application.
At the connection, ble...
Hi,
I am trying to use the SAADC to periodically sample an input from AIN0 and send the resultant data over a BLE link to a phone. Going through the forums I saw that the...
Hi,
I am trying to debug the blinky example project on the nRF52 development kit.
I have followed the following tutorial: devzone.nordicsemi.com/.../
Building and flashing...
I'm in the process of designing a circuit that requires Bluetooth. So instead of having a separate chip for Bluetooth and processing, I decided to use a Nordic Semiconductor...
Classic C documentation issue. Are the values that are passed by pointer (p_peer_address and p_whitelist) to sd_ble_gap_adv_start() copied into that function, or do they need...
I'm trying to read the 32-bit value of TIMER1, but it seems the value I read is always 16-bit value. When I debug the value is never above 0xFFFF.
snippet from nrf_drv_config...
The peripheral is actually a dual-mode device, with BLE being a peripheral device.
I can connect to this device and discover the GATT services with the nRF Connect iPhone...
What is the minimum and max value that the NRF_RADIO->TXPOWER register can get set to? The datasheet it takes a signed 8 bit for the setting, but what happens if you set it...
Hello,
I am trying to read data from nRF51422 ADC using SDK51 PCA10028 board downloaded with S130. I tried one of existing ADC with Softdevice examples, it seems to work...
I have meander antenna design on my board with matching network(similar to PCA10031).
Since I don't have access to VNA or Spectrum Analyzer for tuning antenna, I am tuning...
I'm building some code off of the twi_master_using_app_twi example which is available in the SDK (v11.0.0).
The two peripherals I'm working on are an accelerometer (LIS3DH...
