Hi, I'm using nrf8001 nordic chip on my project. With some time on the nrf8001 chip begins to send the HW_ERROR with failure on ll_lm.s0.c and line 571. This not crash the board yet, but with more ... (more)
I am working with a Blend Micro Board (Arduino IDE with RBL_nRF8001 sdk), using Evothings. Using the RedBearLab Simple control example I can easily connect to the board. I can receive bytes sent from the boards with ble_write and ble_write_bytes ... (more)
It seems like a really great company, but after exploring and asking , and searching for a good BLE solution, I just can't find a good fit.
So you want a GOOD processor, and BLE . If you go with the ... (more)
We have to pick a BLE very quickly , and up till now we used to work with modules which are expensive in mass but easy to work with (e.g RN4020)
I am looking for a chip with a VERY ... (more)
In the schematic presented in the topic 17.1 (dc/dc converter, image below) of the nRF8001 datasheet it isn't shown that AVDD should be connect to a power supply as in the topic 17.4.
dc/dc ... (more)
I'm trying to save power on my HID keyboard application by disconnecting the Bluetooth link after some time of inactivity. As soon as there are keystrokes to send, the device advertises again and sends the pending values.
Generally I ... (more)
It's my first post here so let introduce myself : I'm a 25 y.o. French electronics engineer and hobbyist. I also like skating (inline skates and ice skates) mainly slalom, jumps, speed run, street ride... And I ... (more)
I have successfully implemented the UART over BLE. Now I'm trying to implement the HID over GATT for my nrf8001 device. What I'm trying to achieve is lower connection interval of the IOS device connected. The question ... (more)
We have a sensor product that has been in the field using the nRF8001 in no security required, just works mode for over a year. Recently, we had a request from a volume user that requires a secure connection.
In ... (more)
We are a couple of students trying to implement NRF8001 in our project, we made a SPI setup on our Atmega328p to communicate with the NRF.
After sending our setup packages and 3 packages with 0s we ... (more)
I have a problem with NRF8001 modules. I have two similar boards - one with NRF8001C and another with NRF8001D module. NRF8001C board works well, but NRF8001D board doesn't. The RDYN pin is always high. It seems like the ... (more)
While looking for examples, I found a post from 2004 where a user is asking a question about an example code for HID on nRF8001. Is this code still available? Where can I get it?
Here is the original ... (more)
According to Microsoft's instruction on HID touch device, https://msdn.microsoft.com/en-us/libr..., a HID touch device should create a report (descriptor) as below,
0x05, 0x0d, // USAGE_PAGE (Digitizers) 0x09, 0x04, // USAGE (Touch Screen) 0xa1, 0x01, // COLLECTION (Application) 0x85 ...
I am using RedBearLab Blend v1.0. I ran the HID_template and HID_keyboard_template. I can see the device in Win10 advertised as joystick and keyboard. Then I tried to modified the hid_mouse_batt_nordic_works.xml and generate a new configuration as mouse ... (more)
I am using a nrf8001 and the arduino aci library ported to work with my project. I have started from hello world example. Connecting to the device from android app, sending some data over the uart and then disconnecting seems ... (more)
i am using a blend micro with nRF8001. and i am using it as a hub in my project.Now i am getting a range of 13 meters.but that is not enough for my project.so can i increase ... (more)
I'm using an NRF8001 with an ATMEL ATMEGA 328P (the microcontroller from an Arduino). I need the microcontroller to go to sleep, but still allow the BLE chip to advertise and wake the microcontroller upon connection. It seems as ... (more)
I am much obliged for your kind assistance to me.
I have setup my NRF8001 successfully (please find the setup file generate by the nrfgo attached).
When I ping the nrf8001, I get a standby message ... (more)
BLE Nordic Stack: 0.9.7 Tiny Circuits: Ardunio + Nordic nRF8001 Board
First time post, and hoping someone has run into the same issue that I am. I am in the process of writing a custom sensing ble ...
Hi, i've just started to use the nRF8001, so forgive me if this is an obvious problem.
i'm using the nRF8001 with a microchip PIC processor. i'm using the ace_tl_demo project to test the hardware. On power-up ... (more)
I don't know much about FCC, UL, CE certification and want to learn. I am using the blend micro module which uses nrf8001 chip in my project. How do I get my prototype certified?
I looked around ... (more)
I believe it should be possible to defined a characteristic which can be written to but have no automatic write response ACK sent. Instead I want to send a manual ACK once I have processed the written data ... (more)
Is it possible for one Arduino Uno to have a BLE nRF8001 module and a nRF24L01+ module wired to it (allowing each module to communicate simultaneously)? According to the wiring diagrams, they utilize the same pins. Therefore, will I need ... (more)
I'm developing some code for an AVR MCU with the Adafruit nrf8001 and had a question about the expected behavior of the handshaking lines, REQN and RDYN
My understanding is, once the device comes out of Reset (Reset ... (more)
Hi, I'm planning to add bluetooth LE support to my Arduino based project. I want to use nrf52832, but I couldn't find any example on Arduino interaction with this radio. I know that nrf8001 has an SDK for ... (more)
I recently received a redbear nrf8001 board for use with my Arduino Uno. I had intentions of using it with ANCS. Before I realized that there was a ANCS example included with the sdk from Nordic, I had located someone ... (more)
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 i can see it but when i try to cut ... (more)
I am using nrf51822 as a central device that is trying to connect a peripheral device nrf8001.
I want to build communication bewteen them and use nrf51822 to receive the advertisement data
from nrf8001. Is it possible to do that ... (more)
