I have verified  The maximum channel table size NRF_GZLL_CONST_MAX_CHANNEL_TABLE_SIZE is 32.

but result_value = nrf_gzll_set_channel_table(my_channel_table, 32)   return false

please,help me thank you!

Hi David

Where did you find that? Which SDK are you using? From what I can see the maximum table size is 16 ref https://docs.nordicsemi.com/bundle/sdk_nrf5_v17.1.0/page/group__gzll__02__api.html#ga74ffdf73d8821b39bbed98ca5eeba0fd

Hi,Runnar

Thank you very much for the technical support.

I use example "gzll_ack_payload"  in  nRF5_SDK_17.0.2 . 

One more question: NRF_GZLL_CONST_MAX_CHANNEL_TABLE_SIZE Can  be modified ?and size allow more than 16?

Hi, 

Our departments Gazell experts is out of office. But I did look through the documentation and I could not find anything regarding increasing the size of the table above 16

bool nrf_gzll_set_channel_table(uint8_t * p_channel_table, uint32_t size);

As shown in the code comments，It seems that it can be set  above 16.I want to set the channel table size of 80. Please help me confirm with youre Gazell expert。

Thanks again!
