why use 50ms and 400ms connection interval for testing the maximum data throughput(2M,247byte payload)?
Because 50ms can only send a pdu , and 400ms can send up to 8 pdu...

Hello All,
I am new to this forum, I have been using nRF51822 for a while, and its a great little BLE chip. I am usinga BLE keyboard to send a key to iphone and I captured...
I WANT COMMUNICATION BETWEEN A NRF51422 AND NRF528321 BOARDS, IN WHICH IN NRF51422 BOARD I WILL MEASURE PWM COUNT(IT IS PHERIPHERAL) AND SEND IT TO NRF528321 BOARD WHICH IS...
Hi,
I've been working on a way to detect and prevent replay attacks when beacons are used for sensor data. This is mostly used for home automation sensors, where I have BLE...
Hello,
I wanted to check the log on nRF52 example codes. Though the code compiles and runs (GCC compiler) I do not see the log anywhere. I tried connecting the device ...
Hello,
I was going through the schematic of PCA10040 and I see that the nRF52832 is interfaced to an ATSAM3U2CA-AU. I was under an assumption that nRF52832 itself is a...
We have a custom PCB with the nRF52 MCU.
Our application uses BLE. Thus, we need to program first the SoftDevice. In our case, we are using nRFgo Studio.
Normally, when...
Sorry to ask again, but even after looking for some time at all the marketing material and the forums, it was hard for me to find out what BT 5 features are really supported...
Hi,

Hello,
I am using pca10028 and sdk 12.2. I want to scan the nearby ble devices and want to display the mac address using uart. So which code should I refer or which thread...
I am doing some custom work, and have discovered an odd bug, that I can not seem to figure out.
On the tx radio, I am transmitting a BLE ADV packet with the first 3 bytes...
On nRF52, I see that 100 kHz gives a SCL period of 10 us which is correct but for 250 kHz, I get 8 us instead of expected 4 us. Similarly, for 400 kHz I only see 5 us instead...
I have a case where a module that can perform bit clears in the UICR needs to execute while a Soft Device is present and enabled.
I am aware that any direct flash access...
Hi Nordic and fellow developers,
I have been working on upgrading the nRF51822 QFAA s110 and upgrading the soft device to work as s130 for its (simultaneous Central/Peripheral...
Hello!
I'm trying to read data off of a commercial blood pressure monitor (Qardio arm) using an nrf51822 with the nrf51 SDK v10.0.0 as the central role (s120). I am able...
