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 all,
I'm trying to get TWI working on the nRF51 DK but it's not working.
I used the twi_hw_master_sd.c file so softdevice use should not be a problem.
When I debug...

I succeeded to made the BLE DFU example of SDK 8(bootloader\pca10028\dual_bank_ble_s110) with softDevice 8 working on PCA10001.
Now I want to try DFU over UART.
I follow...
