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...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Bug in the SDK function below. channel_free is called whether or not pin_in_use_by_te() is true or not. For us this resulted in channel_free() getting called with an invalid...
in prj.conf, i add below:
CONFIG_BT_USER_DATA_LEN_UPDATE=y CONFIG_BT_CTLR_TX_BUFFER_SIZE=251 CONFIG_BT_CTLR_DATA_LENGTH_MAX=251
in att_internal.h , change # define BT_ATT_DEFAULT_LE_MTU...
Hi!
I wonder how can I measure the delays, latency, errors and connection speeds. I'm using nrf samples for bluetooth peripheral_uart connect it with nrf connect app. I...
I have a SPI Master and a SPI Slave. The Master will randomly pull data over SPI from the Slave. The slave will randomly generate events that result in data to be sent to...

Hello, Support team.
Our boards do SPI communication to read sensor data.
Basically It works well. I checked that It operates more than 5 hours.
But only one board...
Hi,

Hi,
Is it possible to add four pairs of resistors between the debug signal lines and the connector as shown in the figure below.
Would such a connection not impair the...
The Google Fast Pair Service has recently been included in a number of Bluetooth peripherals (Headphones, fitness trackers, etc.) and has been getting rave reviews.
Has...
I am able to download simple blinky program on my custom board. It is working fine. Custom board is interfaced with nRF52-DK through P19. I am using embedded studio as IDE...
Hi, on nRF5340 I want to capture accurate timing of external events. I need a kind of real-time capture module to read the time period of a pulse train generated by a rotating...
Have a few questions about ble_app_uart example.
From the way I see it, it sets uart_event_handle as the callback, and every time there's an "event" that takes place...
Hello All,
Method 1: I am writing a test application to read the ADC data at a specific intervals(10 samples for every 5ms interval for every 50sec). I am using blocking...
Hi,
We are implementing a synchronous light flashing of multiple devices, so:
1) Can we get a millisecond level (< 10ms) time synchronization by parsing the Link Layer...
Hi, all
I added a scanning module to the example 'ble_app_uart.c', so each one works well.
What I want to do is advertising and connect at the same time while connected...
