I am working on ble mesh with sdk17.0 and sdk5 for mesh I want to send large data vai ble mesh I followed this post https://devzone.nordicsemi.com/f/nordic-q-a/71105/sending-ascii-bytes-through-mesh-between-a-nrf52840-development-kit-and-two-dongle and…
Hello,
I have previously created a product using the nRF8001 chip a year ago using a PCB antenna design. At the time the enclosure for the PCB was RF transparent and the antenna was working nominally. A new revision of the enclosure had to be produced…
Hi there,
When I program my nrf24le1 in Keil uVision, I notice that when I load the program to the flash memory of the connected motherboard6700 with the nrf24 radio module on it, it generates a nrfgo studio nrf8001 file. Does anyone know why this…
Hello,
I am using ADuCM350 microcontroller with a build in Bluetooth NRF8001 on board for a school project. I want to program the bluetooth connectivity over SPI0. I will appreciate some resources about the drivers and how I can program the communications…
I'm building a BLE Peripheral device using Arduino and Adafruit's nRF8001 BLE module. I can find and connect to the BLE Peripheral using any number of iOS BLE discovery apps but for some reason, my late-2019 model Mac Mini cannot see it. I'm trying to…
Hi all,
I am using a nRF52840-DK as SPI slave with a MSP430 as host SPI master for a nRF8001 replacement application.
As I am absolutely not familiar with high level functions (threading, etc.) used within zephyr\samples\bluetooth\hci_spi\, I would…
Hi, I'm about to perform an RF-PHY test on a module using nRF8001 to get a QDID. In that connection, I would like to know the specifications of the nRF8001.Can you tell me about the "?" Below?
IXIT Reference

Hello,
In a quite particular configuration, the nRF8001 sometimes stops responding. The only way to make it work again is to do a hardware reset using the reset pin of the transceiver. Is there a workaround to prevent the freezing?
HW-Setup: MSP430…
I see the NRF8001 doesn't necessarily require the 32.768 Khz oscillator to function. My understanding is it's useful to preserve power. If I'm not worried about power draw of the device, is it fine to leave out the crystal and use the internal oscillator…
I've made a circuit using the NRF8001 but slightly deviating away from the original PCB example. I'm getting the device to go into "Advertising Started" but I can't pick up anything on a phone scanner.
I'm using the 2450BM14A0002T Johanson Balun instead…
I'm using the NRF8001 with a Teensy 4.0. I've been able to find a port of the Arduino library for the Teensy here ( https://github.com/tato123/nrf8001_arm_support )
I'm trying to send a bunch of data in 20 byte chunks to my android phone very quickly…
Hi,
We have successfully created a PCB layout with a PCB antenna following the reference schematic provided by the nrf8001 datasheet. We tested and it is working fine. However we would like to add an option to the user to insert an antenna to increase…
Dear all,
we produce a device using NRF8001 and never had any issues before, but since last Friday, we cannot connect the device to Windows 10 (build 19041) via bluetooth any longer and we always get error messages to remove and try again to establish…
I'm looking for a low energy communication method for a wireless PIR motion sensing device. The system will be battery powered so RX current draw is particularly important and must be as low as possible. The Tx part of the system only be powered on during…
I am using a custom board with nRF8001, where I use external interrupt from the RDYN pin to let MCU know BLE has an event. MCU can recognize these events and change the associated flag. Problem is whenever I have an event on the RDYN pin, BLE draws about…
Hi, i must change IC nrf8001 to IC nRF5x. Is there an easy way to do this? I need the same same protocol of nrf8001 running on nRF5x for compatibility but with the possibility to use eventually more features of bluetooth 5.
Best Regards
I get ACI_BOND_STATUS_FAILED_ENCRYPTION_KEY_SIZE error when I try to bond my nrf8001 peripheral to my iPhoneX. The min and max key sizes are set to 7 and 16.
Any Idea?
Hello,
I am currently designing a custom PCB with the nRF8001 chip. For a smoother assembly and component procurement, I am looking to make all the resistors on the board a standard size. I saw that on the datasheet the resistors were listed as 0402…
Dear community,
We are testing a nRf8001 Implementation, DTM transmitter Test with continuous unmodulated carrier.
In the PS 1.3 / 22.5 i saw that the dynamic data is lost when entering Test mode.
The Test results are unexpected, we have no explanation…
Hi,
I have tried changing the connection parameters (min and max connection interval) and looked into nRFGo Studio to see what the current consumption would be. In Column 2, I have the result from the nRFGo Studio. However, when I used it in my board…
I am currently using nRF8001 in my board (configured to connect - send data - disconnect - sleep every 30s cycle time). However, I am measuring about 140uA in average and I want to lower it further to less than 100uA and I have been getting suggestions…
Hi guys,
Do you have any suggestions on how I can lower the power consumption. I am currently connecting - sending data - disconnecting .
I have the following set the parameters as: Min/Max Interval = 15/15, Slave Latency = 0, Timeout = 3000 ms…
Hi,
According to the datasheet:
Does this mean that when i change my vdd from 3V to 2V, then the current peaks will be reduced? If so what does this:
graph means?
This shows me that the as I increase my supply voltage, the supply current reduces…
