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...
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:
for (;;)
{
uint32_t err_code;
if (!no_more_soc_evts...
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.
I'm getting a little confused reading through the sample application...
Hello,
I am working with the GPIO tasks and events feature on my nRF52832 DK. And I noticed some strange behaviour. I want that two Pins will toggle if some timer events...
Hi,
Please help me with the following theoretical situation:
I have a NRF52832 running HID profile, mostly sleeping.
From time to time, an external interrupt occur (GPIO...
