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...
when we pass the BLE event handler as a function argument to BLE stack init function and register the function results in a deadlock mechanism. Is that we cant able to register...
Hi Guys,
I have a general question to the mesh functionalities. We built a mesh sensor network and I now want to now if it is possible to decrease the data-rate to increase...
Hi,
I just completed the migration from mesh sdk 2.2.0 to 3.0.0.
After running the project it get stuck at line 422 of timeslot.c in function timeslot_sd_event_handler...
Hi all,
So I've developed a custom board with the NRF52832 qfaa e1 and using Mbed OS 5. System on current is around 3.5uA when not using BLE.
When using BLE my idle current...
I'm learning NRF51822.Now,I want to develop it with PC.I need connected Nrf51822 & PC with Ble.What tools can I use? .I designed a Nrf51822 pcb based on CH340.
Hi,
I am using nRF52840-QIAA-T in my design. I am curious to know if Engineering B modification is implemented in the mentioned package.
Thanks in advance.
Hi i used nRF52840 Preview-DK and i try many example with SDK provided.
the problem is the range of transmission too short . can you help how to set power transmission of...
I’m creating an IOT device with some unusual needs when compared with typical home automation. I wanted to ask if anyone knew of a mesh protocol (Zigbee, Thread, BLE Mesh...
Hi All,
I am working on the NRF51822 development board, using KEIL-IDE for the code development using SDK version 10.
I was trying to develop the serial communication...
I'm coding a feature to measure the battery voltage via the internal VDD with an ADC.
The result I get from a 2,75 voltage source is 170.
