@vikasjee Apologies for the late reply. This issue is not related to MYSController:
The debug log hints to some issues with the radio (range, connection) and/or power supply (node does not receive the find_parent_response message), please double-check the wiring, power supply (appropriate caps on both, GW and node), change the distance between GW and node, or try with different radio modules.
@vikasjee What build are you looking for?
@siod Seems like something is wrong with your GW - either GW is not working or too many connections.
@nick-van-alst You need to install the MySensors Board definitions, please follow the instructions here | section "Other configurations"
@core_c Yeah, did a few changes to the MySensors core & RF24 driver to have it running on ATTiny85 - however, the features are pretty restricted.
As a valid & compact alternative, I suggest looking at nRF24LE1 (=SoC RF24 + CPU, ~3USD): http://www.ebay.com/itm/NRF24LE1-NRF24L01-MCU-Wireless-Transceiver-DIP-RF-Wireless-Communication-Module-/112109743951?hash=item1a1a42ef4f:g:~qgAAOSwal5YGFlQ
You'll find additional information and PoC here.
@juanmrodrigues It's still on the backlog 
@romeo01 Thanks for reporting, this is a known issue with build 3314 and lib 2.2.0: The msg parser requires some changes - build 3316 is in preparation (also supporting new 2.2.0 features).
@dirkc If you are using MYSBootloader there is no need to define MY_OTA_FIRMWARE_FEATURE since the FW update happens offline, see here for additional infos.
