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 have some problem. My code was working and everything was fine, but I decided to improve my program. I made some changes, and now TX_DS interrupt on PRX side doesn...
Hi.
It appears that the common gcc makefile in the current SDK does not work for S120, or S310. Please see the patch that fixes the problem.
Tested with S120 and blinky...
We are looking to add some device info into the advertising package, or scan response package depending on space. When looking for a way to do this in a standardised way I...
