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...
Hi,

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...
Hi.
I'm working with both custom board based on nrf52840 and nrf52840-dk.
I just moved from the app_uart api to the abstract serial api.
I have noticed that when an...
Hello,
I am using nRF52840, SDK_16.0.0, SoftDevice S140 V7.0.1 and Segger for flashing the image. I am using ‘ble_app_beacon’.
1) ‘ble_app_beacon’ will only broadcast...
Hello Devzone:
Would I be correct if I assume enabling APPROTECT should prevent writes into UICR? - for other readers, NO, IT CANNOT PROTECT AGAINST SOFTWARE READS/WRITES...
I am in the process of adding central functionality to ble_app_buttonless_dfu on a PCA10056.
When I call nrf_ble_scan_filter_set, the resulting builds debugging is broken...
Hi, I want to use the ADC peripheral (SKD16) and I am looking for the most energy-efficient way of doing this. I design a prototype that will be based on nRF52840 IC and will...
For a temperature sensing application, I am trying to implement a TWI interface with a TMP116 temperature sensor. I am using Keil uVision 5 to write the program. I have been...
I am attempting to port a BLE application to the nRF52840. The original application used a standard HCI serial interface so I am trying to adapt that to use the Nordic SoftDevice...

Hi I am using NRF52 board to interface analog sensor and this board further transmit the data ro sink node. I am using saadc example but unable to get callback or my interrupt...
We have a set of custom boards I am working on debugging. I was able to get our software onto the device via nrf jprog tool by uploading a merged hex file (with SD + bootloader...
Hello,
I would like to turn off the logging to UART0 completely on my custom device.
In the past, I have been able to do this using various config options and reduce the...
Hi!
I am currently playing around with the example combining uart and MQTT from this thread , and it seems to work okay. But when i try to send more than 10 characters over...
My end goal for development is something like the following.
Master sends 0x00 slave sends back 13 bytes of data. Master sends 0x01 slave sends back one byte of data....
