Can't reach the child on level 3

[diygoodies]

Hi I made four absolutely similar boards with stm32 bluepill and nrf24l01 onboard. And on this moment I want allign them in line and to make connection from base 00, thry child 001, then thry child 011 up to child 0111. Now I have sucsessfuly reached only level 2 chlild such as 011 and 021, level 3 and a child 0111 or 0211 stays unreached for now. The level 3 board is absolutly workable I chechked it on level 2. Here is my code examples. Please give me a advise what can be wrong.

I would suggest testing with slightly modified examples or enable debugging to see what is going on for yourself: https://github.com/nRF24/RF24Network/blob/master/RF24Network_config.h#L56

[diygoodies]

/** Debug Options /
#define SERIAL_DEBUG
//#define SERIAL_DEBUG_MINIMAL
#define SERIAL_DEBUG_ROUTING
//#define SERIAL_DEBUG_FRAGMENTATION
//#define SERIAL_DEBUG_FRAGMENTATION_L2
/************************************/
Doesn't make any changes, any additional debug info doesn't appear

[TMRh20]

Crap, the debugging output uses printf, I guess its not enabled on STM32.

You could try the available libraries like LibPrintf to enable it, but I'm not sure if it will work without additional modifications due to the use of program memory related functions. ( see nRF24/RF24#414 and https://github.com/nRF24/RF24/blob/master/RF24_config.h#L155 )

[2bndy5]

Damn, I just came across a blog post about getting this library working on the STM33F10x. The only problem was addressing the printf problem. It was an old thread (~2016). I'll check my browser history and report back

EDIT: sorry it was a dead end

Ok I've made it work. Just swaped NRF modules between 011 an 0111 children. I have no clue what is the difference in that two modules. https://youtu.be/Sr2gImN_1ow

@Avamander @diygoodies This issue is resolved. Probably a power issue related to either using batteries or using a breakout board for the nRF24L01+ (as seen in the video) -- ultimately it was a hardware problem. So, please close this issue.
