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...
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'm using Python bindings 0.5.0 and the connectivity app. On one of our machines that is running tests with the satck/dongle we see it fail a lot with a scrolling of this...
I want to extend the ble_app_multilink_central for pca10028 Example to be able to communicate with a sensor via SPI and then initiate a connection with another pca10028.

I'm trying to discover a vendor specific service that has 7 characteristics. However, when I increase BLE_DB_DISCOVERY_MAX_CHAR_PER_SRV to 7 , ble_stack_init() hard faults...
Is it possible to use PPI and RTC to turn the HFCLK on or off ? (external Xtal)
Example - something like this ...
NRF_PPI->CH[9].EEP = (uint32_t) &NRF_RTC0->EVENTS_COMPARE...
hello,
when I use the chip nrf51822(3rd generation),I find that when I open DCDC function,the ability of chip receiving msg is weaken.the receiving distance is shorter a...
I am doing a blob read on two s130's with s120(central). I am getting BLE_GAP_EVT_CONN_PARAM_UPDATE event while doing a continuous blob read.
Some times i get BLE_GAP_EVT_CONN_PARAM_UPDATE...
Hello,
Can you please provide full schematic for nRF52 dev board. I looked though the documentation and there are small bits of the schematic, but I didnt find full sch...
Using a nRF51822-QFAC-A1 on the nRF51-DK I noticed unexpected behavior when starting the HFCLK and LFCLK in rapid succession. This variant reproduces the problem at startup...
I would like to have 31 bytes for my own in advertising and so far I have disabled everything except adv_flags (it still takes 3 bytes cause of length, AD type and value)...
Hi there,
just wanted to know what the practical differences between the JLINK and mbed MCU interface firmwares are.
From what I experience I can only use the UART over...
Hi,
I'm writing a service to send indications on a couple of characteristics that are part of a service. In order to determine whether indications have been enabled or not...
Hi,
Is there a smaller version of the desktop 2 firmware? I don not need firmware for NFC only ble 4.0. Also would like less complicated pairing. The 6 didgit code is unnecessary...
