Hi all,
Someone can give me a information about the difference between function uint32_t err_code = sd_ble_gap_adv_stop(); and stop the advertising with using the timeout...
hi everyone i'm using 9 axis imu sensor with the nrf51822 board and i'm confusing in how to calculate the roll,pitch and yaw values,can you please suggest me some methods...
I recently purchased the NRF52832-QFAA Nordic SoC, and am having trouble finding information in the documentation about FCC ID and CE mark testing. Thank you.
Hi, I'm trying to implement SOFTDEVICE_EVT_IRQHandler as in HRS example,
this is the handler source part:

I want to create voltage divider for ADC input so I need reference voltage for it. I was wondering if I take it out from DEC1 pin? Any how if I measure voltage from DEC1 pin...
I am developing an application on nRF52 wich simultaneously acts as a central and peripheral and I am using the Peer Manager to manage bonding. The central needs to stay connected...
I have the PPK measuring a custom nRF52-based board. The board consists of the nRF52, a I2C sensor, and bunch of caps (210uF worth). We built a custom board to do current...
We highly anticipate it will but wanted to ask here before we might ask Nordic Support to confirm that the nRF52840 will make use of the ARM TrustZone CryptoCell to provide...
I'm looking to design power management circuit for a 3.7V Li rechargeable battery powered wearable sensor design. Any such reference design would be greatly helpful!
Thank...
I'm developing a device that's supposed to establish an encrypted connection with an Android device and I've gotten PM_CONN_SEC_ERROR_PIN_OR_KEY_MISSING during connecting...
I have the Type 4 Tag sample application running and I can read and write the tag without any problems.
