Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
i made this project to try to create RSC service on arduino
developer.bluetooth.org/.../runningspeedandcadence.zip
unfortunately the server starts but i'm not able to...
Do we need to explicitly set the ENABLE field (Bit31) of RADIO->OVERRIDE4 when applying the override values from FICR->BLE_1MBIT[n]?
From the few samples I've checked,...
Please teach me the minimum theoretical value of the transmission time in the following conditions.
CPU --> nRF24L01 --(2.4GHz/1Mbps)--> nRF24L01 --> CPU
CPU -->...
I need to send a long (let's say 10Kb) notification from Bluez 5.37 on my Linux device to a mobile phone.
My implementation is based on src/shared/gatt-server.c .
I...
Hi,
I have put in my chip (nrf51422):
-1 softDevice s110 8.0.0;
-2 application (hrm_whit_dfu);
My problem is:
when i send characteristic to start advertising the board...
Hi everyone,
I am new to nRf series and have just started to use the nRF51 Development kit(nRF51422). I am using the s130 softdevice and I have seen that the sofdevice supports...
I'm trying to test out pin change interrupts using the PCA10028 dev board. I'm using two buttons to turn off and on an LED. The code below is only generating events from button1...
I have a custom board designed which implements a Arduino Micro (ATmega32U4) and an nRF8001 chip based upon Richard Clarks' nRF8001 breakout . The Arduino FW uses a slightly...
Hi.
Is it possible to enable the encryption of data which corresponds to the particular characteristics? i tried with BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM, for setting the...
Hi,
how is the new nrf_drv_twi supposed to be used for reading registers?
The sequence for that is pretty much industry standard:
> Device address
< Ack
> 0x00 (register...
I'm running the ble_hrs example provided on my nRF52 board. The thing is, I'm unable search my device using both nRF Master Control Panel and normal Bluetooth connection from...
I am using a central S130 softdevice in an nRF51822. I connect to a peripheral using sd_ble_gap_connect(&m_peripheral_address, &m_scan_param, &m_connection_param) . If it...
I am trying to provide a custom peripheral service with a 128-bit UUID in an nRF51822. I would like to use two bytes of the UUID to encode a piece of information unique to...
Hello,
am I right to assume that if sd_ble_gattc_write returns anything other than SUCCESS, then the packet was not queued?
Is this also true for BLE_GATTC_EVT_WRITE_RSP...
Hey guys,
I have a little problem on a new board comunicating with a MPU9250 sensor.
Chip version is nrf52832-QFAA-BA
GPIO PINS Used P0.20 (SDA) and P0.21 (SCL)...
