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 using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
Hi
I am trying to start an advertise. If I use the “BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED” flag all work’s pretty fine, but whenever I change the flag to “BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE...
Is it possible to have a fast advertisement interval (for connecting and bonding/pairing) for example: 40msec; at the same time, have a slow connection interval (after connection...
uint8_t flags = BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED |
BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
And then when I look up "BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;...
Hallo,
i'm trying to test my BLE aplication using the PTS. The profile test are mostly OK. But if i run the GAP Test (especially TC_BROB_BCST_BV_01_C) the PTS does not...
It seems that static and global data is NOT set to zero during start-up. This is supposed to happen according to the C-standard. How to do this in a proper manner, i.e. to...
Hi All,
we currently move our custom design to CE testing and already did some successful EMC pretesting.
However, our testing house asked us to prepare a firmware for...
Hi All,
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...
Hello!
I am working with the example mpu interface projects located at the following repo:
github.com/.../nrf5-mpu-examples
After converting the Keil projects to...
Hi,
After I've successfully connected my smartphone via nRF Toolbox's UART-BLE Service to my nRF52 peripheral, I tried to mimic the scenario when the devices get disconnected...
Hello
I want to understand how far the firmware that is burnt on to a Hardware is protected. Is it possible to actually read the firmware from a device (if the device has...
Services Setup
I am trying to feed the "Services Data" manually to the nRF8001.
As per the data sheet page 82 (see image below): Upon transmission of 1 packet of data...
I am trying to run the ble_app_beacon example on an nrf51802 device.
The call to sd_softdevice_enable() never returns (jumps to 0xFFFFFFF9)
The fault handler is not called...
My guess is that:
Characteristics are (or at least, can be considered) subsets of services, which in turn, are (or at least, can be considered) subsets of profiles.

Hi, I am modify the S120 multi-link UART example code (code is available here ), and just noticed a problem that the central is only able to send the UART data to the last...
