I've recently began experimenting with the HID service and connecting to iOS devices in order to achieve lower connection intervals with Apple products (as described in their...
Hi
I have a question about using gazell link layer and paring library with concurrent timeslot api. I try to do this but i have the hard fault handler after invoked nrf_gzll_init...
HI,
I want to use PWM to control various hardware (LED's, etc ..) so I started off from the suggested PWM code example, found in this forum + modified it as I want to use...
hello,
the function ble_stack_init () in the example of ble_app_uart are quite different from that in the example of ble_app_proximity in my first sight.
ble_app_uart :...
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...
