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...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
Hi all,
I am developing an application for a product where power consumption is critical. The application is bundled with the Secure DFU bootloader. I noticed that the bootloader...

When I migrated, the reference routine output PWM, but kept reporting errors. I have also changed the relevant definition, but I still can't. Has anyone met it? Thank you...
Hello,
We're evaluating the Laird BL654 using your nRF52840 (to be precise, we're using two DVK-BL654-1.0 development kits).We tried to use the 'blinky' examples (ble_app_blinky_c...
Hi everyone,
I am developing a remote controller using nRF52832 chip. My prototype is currently developed in PC10040 board. The IDE is Eclipse Oxygen, and the SDK is S132...
Hello, everyone~
I plan to use the Low Energy Secure Connection funtion with nRF51822. But when I build the lesc example in SDK 12.3.0 (ble_multirole_lesc), there's a error...
Using the sdk15 and softdevice 132 v6, I'm setting up an app to read and write to an SD card that uses SPI1 (SPI0 is used by a display). Everything is working great, except...
Hi,
What's is the max length for the payload data in "mqttsn_packet_sender_publish" method?

Redefining my question above: What's is the max length for the payload...
Hi Sir,
According the table 19.4.2 of 52832 datasheet (v1.4), there is a start up time (0.36 ms) for HXFO.
How do I measure the start up time of my 32M crystal?
If...
Hello,
While an attempt to develop solid security mode bulded around Root of Trust starting from RTL and Device root key we found that unfortunately, it is mentioned in...
I would like to detect if a reset happened due to a brownout or an actual power off.
I tired so far using the GPREGRET and RESETREAS registers. They are useful to detect...
I have an app that works perfectly when run from the debugger, but not when started by HW reset. We use the serial port to communicate to a control processor (STM32) The Nordic...
Hi,
I was trying to test a slot circle antenna with nRF52832 which is well matched to 2.4G~2.48GHz, but it is circular polarized antenna with high directivity.
However...
Hi All!
I use nrf51822 with sd s110 to send data to android phone with sd_ble_gatts_hvx. If sd_ble_gatts_hvx returns NRF_SUCCESS then that packet get to TX buffer. I didn...
With nRF5 SDK v15, the code size became too large for the free version of UV5 , Is there a way to reduce the code size by reducing some array size or commenting something...
