Yes, the code chains mbufs together so that if you have data length extension
enabled you will be able to send larger PDUs (and receive them as well).
Note: there is a limit on how small the mbufs can be with nimble as the
controller code assumes contiguous space for certain types of packets
Hi
If Nimble with LE Data Packet Length Extension feature enabled, would mbuf
block size of 100 still work? Could a PDU occupy more than one mbuf (e.g.
two consecutive blocks)?
Best,
Khaled

Hi Will, hi Chris,
thanks for your hints. I thought it would be less risky only to reduce the
counts and not the size of the buffers.
I tweaked a bit with the values of MSYS_1 and found this is working for my
current app:
MSYS_1_BLOCK_COUNT: 10 # was 12
MSYS_1_BLOCK_SIZE: 180 # was

Another thing with the nimble stack. The mbuf block size of 292, which Chris
shows reduced to 200, is much larger than it needs to be. I am not sure what
the smallest size actually is, but you can set it to 100 bytes and it should
work. This can get you more buffers and/or reduce your
Hi Alfred,

Hello all, I’m experimenting with mynewt for several weeks now and I’m
especially impressed by the statistics, logging and image update functionality.
I’m having problems with getting all the statistics using newtmgr via BLE.
I took bleprph as base, added ADC and enabled several stats, logs and
