Light switch nRF5 on SDK for Thread and Zigbee v3.2 will not join network

Question

Hi, 
 As simple as the title! I have tried to move my code from sdk v 3.1 to v3.2 but it will not join the network. 
 Back to basics and using off-the-box ligh switch example. Also, this example will not join the network (testing with a smartthings hub). 
 I have also detected a issue when setting the device as sleepy end device. I have changed the following on the example: 
 - On line 551: 
 {
 zb_zdo_signal_can_sleep_params_t *can_sleep_params = ZB_ZDO_SIGNAL_GET_PARAMS(p_sg_p, zb_zdo_signal_can_sleep_params_t);
 NRF_LOG_INFO("Can sleep for %ld ms", can_sleep_params->sleep_tmo);
 zb_sleep_now();
 } 
 - On line 601: 
 //sleepy_device_setup();
 zb_set_rx_on_when_idle(ZB_TRUE); 
 Not sure if this related to the main issue, but the device will report a sleep time of 998ms but it will not sleep for that time. I will just keep reporting the sleep time but not going to sleep.

Hi Armand, 
 Did you check that the light switch is using the same Zigbee channel as the Smarthings hub? And can you attach the sniffer logs so I can see what is going on between the two? 
 And I just want to add that the main goal of the examples on the SDK is to demonstrate different features of the Zigbee stack, and unless it is explicitely said so on the testing instructions of the example, they are not intended for use with 3rd party devices such as Smarthings hub right out of the box. This doesn't mean there is an "issue" with the stack, you just have to modify the example for your intended purpose. 
 For instance, you should set the IEEE_CHANNEL_MASK (located in main.c) to cover multiple channels if you are not sure which channel your Smarthigns hub network is on (all of our examples use only Zigbee channel 16 as default). Set IEEE_CHANNEL_MASK to 0x07fff800U, in order to use all 802.15.4 defined channels as indicated here . 
 For the sleepy end device issue look inside sleepy_device_setup(). When putting the device into sleepy mode you need to press the SLEEPY_ON_BUTTON so zb_set_rx_on_when_idle is set to ZB_FALSE (RX off when idle, see here and here ), in your code zb_set_rx_on_when_idle is set to ZB_TRUE. 
 Best regards,
