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...

According to nRF52832 Product Specification v1.3, tPOR is written as follows.
Is the VDD rise time range from 0 V to 1.7 V or from 0 V to 3 V?
Please tell me the range...
Hello,
I'm trying to change advertisement packets, I found this link text
it says:

Hi, I'm trying to change ad packets in the blinky example. I want to be able to keep blinking but change the ad packs (don't know if this make sense, but main goal is to change...
I have created a build system that will install openmesh on simblee chips, and it appears to be mostly working. However, range is very poor, like max 2ft. I have tried adjusting...
Hi guys,
I am working with a central battery powered so, I am controlling the RF activity calling scan_start() or sd_ble_gap_scan_start() and disabling the RF activity...
Hello,
We are switching chips from the nrf51 to the nrf52832. I have a nrf52-DK board now. My Eclipse set up is still able to compile, run, and debug my nrf51 projects...
hi,
im a little lost with BLE at the moment. all i want to do is sending 3 bytes of data (sensor data) approximately 10 times (+- 5) a second (when the uC is not sleeping...
As a central, I am writing to a variable length characteristic, advertised by a service of my peripheral. In this case, I am sending 80 bytes of 0x01 as a test
uint8_t...
I used the ANCS program in sdk12.3.0, I have closed the white list function, I use the iphone connection and paired, then I ignore this device on the phone, and then I use...
Hi
I am using nrf51-dk board along with the S130. I am getting the following message when I debug my code. The central link count is set to 0 while peripheral link count...
Hello,
I didn't find much information about how different settings for the MTU size behaves with older versions of BLE devices. I'm using the softdevice s132 4.0.2.
