Hello all,
I have a question regarding the nimble stack.
I'm working on a BLE test framework to evaluate BLE and different stack
implementations.
Nimble is already implemented into the framework for small experiment
setups, but when I try to run a experiment with more then two peripherals
with the nimble stack, I get the return code `BLE_ERR_CONN_REJ_RESOURCES`
from the function `ble_gap_connect`.
When looking at a packet log of the HCI communication I see, that the
controller responds with command status `0x0d` (Connection rejected due to
limited ressources) to the `LE Create Connection` command.
The thing that is confusing me is, that the same experiment works with a
different stack and the packetlogs do not look signifficantly different
between the two stacks.
My first problem for experiments with multiple peripherals was, that the
`MYNEWT_VAL_BLE_MAX_CONNECTIONS` parameter in the config was set to 1.
That was my mistake, but I fixed that.
My question is if there is a different configuration parameter that I'm
missing or if you have a different idea what could be the problem.
For additional information: The test devices in the experiments are
Raspberry Pi 3s and the nimble build is based on the linux port from the
repository.
Thanks in advance
- Christoph
