I'm just new to BLE, but from the 100 examples, maybe #30, 'Time multiplexed central', and #32, 'OOB paring' could help. At least those examples seem to use more than one BLE device (without the dongle) as example base.
Thanks, I also do not have experience with BLE. I tried with Time multiplex example and able to make connection between between different module. Now I want to transfer data between modules. Do you have any idea .how to proceed?
Basically, you will need to create a GATT profile to hold data for the second device to read/write from/to on the local device when they are connected with BLE. Here are some links that will assist:
