I am working on a project using a ble nano (nrf51822) using the Nordic SDK 8.1. In the examples I found a way to control an LED using the methods LEDS_ON and LEDS_OFF. I wanted...
Hello,
I am using ble_app_gls example and I have implemented static passkey in the code. Now I want to see if wireshark shows the passkey when I connect to ble devices. For...
Hi Team,
We are implementing an UART communication between a M4 processor (UART master) and a nRF51 (UART slave) and we want to use the UART in Low Power mode with flow...
Hello everybody,
for my project, i will bond the peripherial with the central.
I test my device with the MCP and can connect without problems. When i press the Bond Button...
Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...
Loaded Softdevice S140, ( Using NRF52840 DK board ) using NRFgo Studio.
App flash base is set to 0x00021000 and app RAM base is set to 0x20003000
Looking at the CPU...
In our earlier projects with nRF51 and SDK 8 we used to have bluetooth device names of length 13 or 14 characters. However, when using nRF52 and SDK 12 I noticed that the...
My app is generating hardfualts. Based on this post I looked at memory location SP + 0x14, which points to the address that generated the fault.
Memory at SP+0x14: 8F 31...
Hello Everyone,
I am doing the rough calculation of the power consumption of NRF51 where in the radio part of the datasheet it is indicating 10.5mA whether it is denoted...
Hello ,
I'm using a couple of nRF52 dev.board (one is Nordic preview dev.kit , the other one is a Rigado BMD-300) , with S212 ant+ softdevice . I'm able to deep-slepp the...
I use the board to act as relay.First ,i scan and connect to one peripheral.Then ,i want to disconnect the peirpheral once the another central connect to my board.i call sd_ble_gap_disconnect...
Hi ,
Would you help me to find right material(App note, source code/project) to implement below case:
My nRF51822 connected on beaglebone black(BBB) over UART this will...
Hi,
I want to implement a DC/DC converter setup schematic for my projet and I don't know how to make the difference between the AVDD and VCC_nRF supply tags given in the...
Hi, all!
I have a Quesion about Maximum Voltage & Current of internal DC/DC conv. & LDO of nRF52832.
I'll design circuit using olny internal DC/DC conv. & LDO of nRF52832...
Hi.
Is there a (lazy) (dummy) comfortable way to make an nRF518 chip (in my case, nRF51822) communicate with the built-in bluetooth adapter of a laptop with windows 7 or...
Hi,
I am trying to connect a GPS through UART to nRF52 and get the reading and write it to the serial USB of my PC. I am using app_uart_init() and app_uart_close(). My idea...
Hi, I would like to handle in the twi_event_handler the case when the p_event->type == NRF_DRV_TWI_EVT_EVT_DATA_NACK differently and not treat it as an internal error.

I'm trying to use separate antplus network key, but I still can receive messages from devices that are configured with another key. Device A was using network key 0,0,0,0...
We are using nRF51822 for our products.
We want to know the min value of "Receiver sensitivity" when we use this chip for BLE.
The Datasheet says "Receiver sensitivity...
Hello,
I have designed m custom PCB and i have verfiy my antenna maching network with the spectrum analyser its is perfect matching but the real problem is when i measure...
