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...
Hi,
I wanted to create fixed rate waveform. I first used nrf_delay_us with nrf_gpio_pin_toggle. But I realized it is not accurate enough to do it, especially when the device...
Hello,
I'd like to know how exactly do i implement this function in my app?
I tried getting the value from response (as shown in documentation) : ble_gattc_evt_char_val_by_uuid_read_rsp_t...
Hi,
My Jlink lite CortexM work with nrf51822 DK boards. But my PCB with nrf51822_xxAA chip can't download code. I'm using ukeil
When I chek in utilities Jlink can't recognize...

Hello,
I am new to working with imbedded chips and could use some help. I am working with a pre-programed nRF51822 chip on a PCB and would like to be able to read the imbedded...
Hi I want to using nRF51822 link with MCU ti-am335x have Linux system(Ubuntu) by standard HCI command, BlueZ or related hci tool.
I know that I can use nRF51822 S120 serialization...
I would like to share my wireshark capture file (pcapng) with another developer to view that doesn't have a nordic sniffer. They cannot see the ble protocol information. Is...
I am able to set the connection timeout to 250ms in the ble_app_hrs peripheral sample, but in the ble_app_multilink_peripheral it will not advertise if I set it below 1000ms...
Hello,
When using the bootloader I've noticed that the booatloder resets after advertising for ~1minute. I'm try to figure out if this is intentional.
I notice that...
Hello,
I am currently designing a project that will advertise as two different beacons simultaneously using the Timeslot API. I have successfully implemented the nRF51...
In my all projects, I am using this code to obtain and set local device address:
uint64_t deviceId = ((uint64_t)NRF_FICR->DEVICEID[1] << 32) | ((uint64_t)NRF_FICR->DEVICEID...
Hello,
I build a Broadcaster(iBeacon) with the DK PCA10028. This Broadcaster sends periodically ervery 30ms a message (I have sniffed the Broadcast message and it appears...
Hello,
I am having some strange results with some firmware I have been developing. I developed the firmware on the nRF51 Development Kit (PCA 10028) and the device advertises...
hi,
i would want to develop a project with master (mobile phone)- bridge (acting as master and slave,nrf board)- slave (nrf board) .
