First time here? Check out the Tour!
I add UART support using IRQ on the "ant_hrm_tx" example code.
and I'm sending packet of 4 bytes that contains: Delimiter,HeartRate,Battery,Delimiter
the frame is very basic and send every 1000ms from another MCU.
the problem ... (more)
I was unaware that the 'manufacturer data' in the advertising packets is limited to less than a full payload. However, whenever I set it to >6 the program "crashes".
#define MANUFACTURER_DATA_LEN 7 ... ble_advdata_manuf_data_t adv_manuf_data; uint8_array_t adv_manuf_data_array; uint8_t adv_manuf_data_data[MANUFACTURER_DATA_LEN]; adv_manuf_data_data ...
Dear Nordic Developer Zone,
Since I have implemented a timer with interrupt in my application, the debug mode if the Keil IDE stops working when I try to restart the code execution after a breakpoint for code analysis.
I am ... (more)
I'm a bit confused. After going through available documentation, I thought I had understood that RTC0 was used by the SoftDevice, but that RTC1 was available to use how I liked. After going through the ble_app_template example ... (more)
Is there an example on how to set up the low-power detection to provide an interrupt to the CPU?
Hi, Thank you for your kindly help.
I have get the result from the register RSSISAMPLE. The result I get from RSSISAMPLE is like this:0x00000050. As you known, the result should be a negative number. So there must be ... (more)
Hi, I am trying to test my UART using some simple loopback test, and I have noticed that the service discovery command of BLE will occupy the CPU a quite long time. I am just wondering if there is any ... (more)
Is it possible through the API/Softdevice to do one of the following:
read out the current advertising data structure, change a the manufacturing data field, and write back; or
only change the manufacturing data field directly
Currently I'm ... (more)
Hi, I am planning to use modules with nRF8002 in an indoor positioning application. The mobile devices that are to be located are continuously scanning for BLE devices and detect the module's advertisements. They do not actively connect, just ... (more)
Hi, we would like to create a kind of game using 2.4Ghz emitters . The 2.4Ghz USB Dongle emits and the mobile phone detects the frequency + embed unique ID/code so we confirm if the person has been there ... (more)
I'm a green hand HW Engineer.
I'm trying to compile, program, and run The Heart rate monitor demo though following the step in nRF51822_DK_User_Guide_v1.0.pdf .
First of all, I confirm that the hardware, wire jumper, and SEGGER ... (more)
Hello! I am trying to develop on the nRF51822 eval board as called PCA10001. The programming interface I use is uVision4 on win7.
I would set a static PASSKEY for the pairing process in the reference code "ble_app_hrs". I add ... (more)
I set up eclipse according to n-AN29 and imported several of the example projects. The blinky_example project described in the nRF51822 dev kit user's guide works perfectly (I get blinking LEDs). When I try to use the heart ... (more)
I am looking for details on the internal temperature sensor on the nRF51822. I would like to use it to get a general ambient reading of the air around the device. Basically, I need to know if this temp sensor ... (more)
hi everyone.now i am developing a project with nrf51822.i am using the PCA10000 dongle to see some information of advertising packages. i moved out and pluged in the PCA10001 many times,but the random address are the some ... (more)
and can user change it?or the hardware does not support BLE_GAP_ROLE_CENTRAL?
i searched many many times,and i can get the anser.what kind of GAP Address type does BLE_HRS demo use.can someone tell me?tks!
I tried changing the define below from 1 to 2, so I could have one handler for a button and a different handler for other sensors. But my problem is: 1. If I set it to 1, the button handler ... (more)
I get following message when I try to program with the Blinky project a nrf51822 chip: "Error - flash download failed - Cortex M0.
What is wrong?
Hi, I have been trying to maximize the baud rate of my uart module, I am using the app_uart layer to control the uart and I have noticed that in your implementation of HCI you have set the baud rate ... (more)
I've developed a circuit with Mikroelektronika's nRF T click module. This module uses nRF24L01P but as I see I cannot order it because it is obsolete.
Should I use nRF24E1 or nRF24Z1 instead of it? In our ... (more)
I have a couple of questions about sending multiple notifications:
1) I want to send multiple notifications (from same characteristic), is that allowed by S110 softdevice?
2) What is the maximum number of packets that S110 could process per ... (more)
Hi, got an interesting problem, this is on a custom board with nRF51822 QFAB that we are bringing up. The radio test (not using softdevice) works ok and produces strong transmit signal (as strong or even stronger than from the ... (more)
my application is a 9-axis battery driven motion sensor with a data rate about 144 bit per packet at 1000Hz i have to transmit over air. Low latency (<10ms) is extremely important. The device must consume as low power ... (more)
I have an ultra low power application that needs to broadcast it's proximity on a 1sec interval. However, about 75% of the day I would like the device to be powered down and not transmitting.. This should be controlled ... (more)
I'd like to use 'Direct Advertising' to get the attention of a Central (a specific one or any in range) when an event happens on the peripheral. Is this mode supported by the device / S110? If so, is there ... (more)
Why some devices makes just an IRK entry in Whitelist of SDK and other put the address into? Is it possible to config which entry should be done?
How are the four RAM banks divided up in the nRF51822? Is it an even split of the 16K total RAM (i.e. 4K per block)?
Furthermore, can I expect strange results if I turn on RAM-retention for the 8K ... (more)
My question is how to configure clock in gazell protocol on nRF51822
I look at the example gzp_dynamic_pairing but that does not have a code part of modifying clock.
I know defining SystemCoreClock on "system_nrf51.c" and i ... (more)
My target board is nRF51822, and I want to run the heart rate demo project, but a error message when I compile it :
