Network formation issue using the NRF52840-DK

[kyh-ly]

problem descript

• last version openwsn-nrf52840DK project can not build by segger embedded studio (have fixed the compile error if you need I can push the branch to you)
• nrf52840DK can not organize network when root the mote(does not show any information while the num of ASN is growth)
• port older version openwsn-fw to stm32f103 + CC1101 development board, using openv-server command and terminal show :

04-TRAN/sock.h has some error, some variable undeclared. Can not find the errno.h file
-EADDRINUSE

for that issue I recently opend a PR https://github.com/openwsn-berkeley/openwsn-fw/pull/533/files

@Chris-Ho @kyh-ly Going to move this to a new issue. Sorry I haven't had the time to look at your PR's. I was busy with some other projects. In the following days, I'll probably have time to merge some PRs.

@TimothyClaeys
Thanks. I have fixed the sock.c error with your reference and nrf52840-DK project builds successfully. The mote can't organize the network after I register the master mote, it stops a long time.

@TimothyClaeys @Chris-Ho Hi, I have ported openwsn to stm32f103VET6+CC1101 development board, and it still can not organize network or join the network. It meets the same problem with nrf52840DK.
How to transmit data between different motes, in uinject.h file I find this file implements the function of sending data from the node to the root. How to implement the receive function. @koalo

Hi，guys. There has some problem when I use OpenVisulizer to set up RPL server:

• the root mote can not work well and the network doesn't organize.
• how to transmit data between different motes.

Hi, guys. If anyone meets this problem when using OpenVisualizer to connect with the mote (STM32f103)?

@changtengfei Even if I increase the value of wdRadioTx , the problem still occurs. I think I should analyze the duration of the TT3 and determine if there is a problem with the timer

@TimothyClaeys Hi, I find that my CC1101 RF has a long time between finishing loading packet and start to send a packet, I think this value is the delayTx. But set a big value to delayTx the code would die in some time, and why this problem occurs and how to fix it?

@TimothyClaeys @remyleone How to add the user schedule on the openwsn
