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...
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...
Hi, as per subject, I would like to know the trade-offs of using the internal DCDC vs LDO when it comes to RX sensitivity specific to the nRF52840-QIAABB variant.
From this...
Hello,
I am using the nRF840 PDK for testing the radio communication.
During my tests, for TXPOWER=0xD8(at minimum), I found a gap of 7 dBm between the radio output...
Hi, I am trying to connect the nrf52840 to GPS module, and I hope that the dk could read the GPS information via UART. I try to modify from this example nRF5_SDK_14.2.0_17b948a...
Hi,
the following are the TX's current consumption for 0 dBm from the datasheet:
I assume the second line refers to the measurements when the internal LDO is used...
Hello,
I know how to update the application through OTA at the moment, I do the following steps:
set the device run in DFU mode by writing 0x01 in Experimental...
Hi, Nordic engineers
I checked there is one error function in nRF5_SDK_12.1.0_0d23e2a:
in nrf_esb.h
uint32_t nrf_esb_get_rf_channel(uint32_t * p_channel);
but in...
Hi,
I have 3 nrf51822 devices. Two of them act as peripheral and one acts as central. Each peripheral is used in a wheel and they are the 2 wheels of a cart. Central is...
The latest Objective Spec nRF52840 Objective Product Specification v0.5.1 got me a little confused since I was working off of v0.5 until few weeks ago. My application is a...
I'm using SDK 12.2 with Softdevice S132 V3.0.
I try now the migration to the most resent SDK 14.2 with its Softdevice, because it seams there were several bugs fixed in between...
I am trying to use a dht sensor and arch ble device to display temperature on the console. But when I flash the program on to the board, I cant see the output on the console...
Hello Everyone,
I have developed my application using BLE for connect android mobile. I have design complete PCB using your reference design. But i have littele confused...
Hi guys,
I follow this link and do the configs on the Keil project in examples\dfu\bootloader_secure_ble\pca10040 to run on nRF52810.
But I find that the micro_ecc_lib_nrf52...
I'm trying to use a the COAP server example from SDK 14.2 running on nRF52DK. I've got a RPI3 acting as a router between my Ethernet network and the 6lowpan/BLE link.
I...
Hello,
I have a custom application and bootloader with DFU support. We have been able to download application updates using the DFU. Today I noticed that I am not calling...
