LP-EM-CC2340R5: NESB Protocol

Hello Danilo,

I would like to confirm with you that the question here is about the payload of the ACK. Or are you also asking about how we can change the timeframe of ACK?

(also what SDK are you using?) 

Thanks,
Alex F

Hi Alex,

Thank you for your response. Please see our customer's feedback below.

I have a question regarding the ACK payload generated by the PRX. 
As I understand it, this happens automatically. Is it possible for me to generate a custom payload in response to a poll from the PTX?
I`m using SDK 9.20

Regards,

Danilo

Hello Danilo,

First if you have not already looked at we have some great documentation about the NESB functions, and the packet format here: Radio Control Layer (RCL): NESB Command Handlers

By default, NESB does have a specific format over the air, we can update the PTX packet itself but it does not seem like we have direct control of the ACK packet itself.

TI NESB User’s Guide — SimpleLink Low Power F3 SDK Proprietary RF User's Guide 8.20.00 documentation

I will try to see if we have any other information about the ACK itself but it seems to be auto for NESB. 

Thanks,
Alex F

Hi Alex,

I've shared this thread to our customer so he can continue the discussion with you.

Hello Danilo,

Thank you for the update! I do want to let you know that BMACK exists (Bare-metal ACK) is a more generic ACK PHY that customers can develop with instead of NESB but if you need compatibility specifically with NESB then you cannot use BMACK. 

You can control the payload info in ACK in BMACKs. 

(You can generate a BMACK PHY with your SDK's Sysconfig its one of the custom options) 

Thanks,
