Thank you for your mail. Luckily I got access to the IOT-Lab testbed and
during past few days, I've been busy getting acquainted with the testbed,
going through the tutorials (RIOT OS tutorial 3 on their website seem to
be outdated as I couldn't find the RPL UDP example under RIOT example
application folder), watched the RIOT-OS introductory video on Youtube [1]
and tried some other example application. So far so good.

I think, I need to spend some more time to get a clearer picture, however
I do have few doubts (probably silly ones right now) and have few areas of

1: Generally vendors provide BSP (startup files; combination of assembly
and C), Libraries and in some cases binaries with some glue logic
(e.g. Nordic Semiconductor distributes Bluetooth stack, ANT stack etc
as a binary, which they call softdevice) for bare metal programming.
Those Vendor specific APIs are not inter-operable. So, Is RIOT-OS an
alternative to such cross platform development ? I mean If I develop an
application for one hardware platform (Say NRF51822, with ARM Cortex
M0 SOC, But with different sets of Peripherals) using RIOT-OS,
how easy it would be to port the same application on another platform
(say, STM32 also with same ARM MCU but with slightly different set
of Peripherals)?

2: It seems that there has been some work already done for BLE
(Bluetooth Low Energy) support. What is it's current status ?

My areas of interest in no particular order are
1: Bootloader for Firmware upgrade over the air.
Some time back, I implemented DFU-OTA (Device Firmware Upgrade
Over The AIR) over Bluetooth transport for a custom board having Nordic
Semiconductor's nRF51822 SOC. Thanks to the Bootloader, distributed
by Nordic, and excellent documentation, using the bootloader with my
application was relatively easy. During that exercise, I understood that
some glue logic was required in the application and the bootloader, and
also depends on some hardware specific configuration. How easy or
difficult it would be to have such Firmware upgrade feature, when
using RIOT-OS ?

2: I've a custom board which has a on-board external Flash memory
from Spansion, connected to STM32 MCU (ARM Cortex M0 based
SOC) over SPI bus. I also looked at the drivers directory of RIOT OS
and so far it seems that no such drivers for Spansion flash memory
connected over SPI bus exist. So maybe this is one of the area,
I can work on ?

3: I've interest in Networking aspects too, however, I do not have
any practical exposure to lower layers such as 802.15.4,
6loWPAN and have limited experience with IPv6.
