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...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
My application is based on ble_uart_app. I want to integrate the DTM so that the nRF51 will be in RF test mode when it receive command from UART. However, I found that the...
Hi all,
We're going to implement floating point agorithms on the new chip which has a FPU (cortex M4F). with the 64MHz system clock, how many flops can we have? I could not...
Hello.
I use nRF52 & mpu9250.
I want to use dmp.
But now it's not going well.
Now, there is no error,but fifo_count doesn't change after fifo_count became 512.
I...
Hi,
sometimes not always, the function peer_id_is_allocated return false and this causes an ASSERT of device, because a NRF_ERROR_INVALID_PARAM is returned by pdb_write_buf_get...
Hi,
We're using nRF51822 and in the future we'll use nRF52832.
We do use bluetooth, but as far as I know, we don't use encryption (code is based on the HRS example, and...
Is nrf52 support 3 wire spi interface? I am using AD9837 3-wire spi module act as slave and nrf52 dk act as master. I am using SCLK, SSn(i.e.,Fsync) & MOSI pins only.I want...
Hi, I’m a newbie of nRF SoC. I have a BLE gadget with nRF51822_xxAC that controls LEDs and obtains data from accelerometers through I2C(TWI) devices. The hex file for the...
Hello,
I am able to get NRFtoolbox dfu code work for iOS 10.3. and now able to perform the DFU on BLE device.
But when I perform the DFU its GAP name changes from Beam...
Hi
I migrated from SDK11 to SDK12/13.
In SDK11 I already had avaiable a softdevice to use for ble_app_uart peripheral.
In the new SDK I have to build the softdevice but...
I'm trying to understand example "ble_app_hts" how after advertising make a connection. I didn't see in code any call of function "sd_ble_gap_connect" ? how is made connection...
I use the nRF OpenMesh from the GitHub. ( https://github.com/NordicSemiconductor/nRF51-ble-bcast-mesh )
My mesh network just has two mesh node, node A and B.
I made A...
Hi everyone!
I want to work with two UART interfaces in my nRF52DK, in one hand, I must receive data sended by one cable which converts USB to serial, for this I use this...
Hello,
I caused a hardfault error and triggered the HardFault_Handler in "hardfault_handler_gcc.c". But instead seeint its source, I could only see the message no source...
