LUA script not working on Express LRS

[julioghigi]

I am using Express LRS with KISS and everything works fine, except by the LUA script. It won't load any number, just stay on "----". I took the same rx and put on a BF board and the BF LUA script is working fine, so I know thta the problem isn't the rx or radio system, just the LUA acript for kiss. Hope someone can solve this or at least tell me how to solve. Thanks in advance.

What protocol is used by LRS? Crossfire? Sport?

ELRS uses Crossfire protocol!

[fedorcomander]

then it should work. if its STRICTLY follows protocol.

Yeah I know, but it won't, BF lua script works normally, is there a way I can debug it? Like see what it is receiving and more?

[fedorcomander]

u can see in lua itself what is sent, and compare it with bf. ;) may be addresses are not ok?

Hello. Give me some help please! What address i shoud use or where i can get it?

If i right understand i need right value in this place:

LOCAL_DEVICE_ID = 0xEA -- transmitter REMOTE_DEVICE_ID = 0xC8 -- flight controller

in KissCF.lua file. Please confirm and make some help.

[fedorcomander]

I have LRS system on the way to me, will check when its here. Otherwise all is done based on PDF from trappy.

Hello Alex! Thanks for your help. Can you send contact @trappy at somewhere?

I try to analize lua from BF and KISS. Can you explain about adresses?

Found in BF - betaflight-tx-lua-scripts/src/SCRIPTS/BF/MSP/crsf.lua

-- CRSF Devices local CRSF_ADDRESS_BETAFLIGHT = 0xC8 local CRSF_ADDRESS_RADIO_TRANSMITTER = 0xEA -- CRSF Frame Types local CRSF_FRAMETYPE_MSP_REQ = 0x7A -- response request using msp sequence as command local CRSF_FRAMETYPE_MSP_RESP = 0x7B -- reply with 60 byte chunked binary local CRSF_FRAMETYPE_MSP_WRITE = 0x7C -- write with 60 byte chunked binary

And found in kissfc-tx-lua-scripts/src/common/KissProtocolCF.lua

-- -- KISS/CF code -- Kiss version by Alex Fedorov aka FedorComander local toolName = "TNS|KISS Crossfire|TNE" LOCAL_DEVICE_ID = 0xEA -- transmitter REMOTE_DEVICE_ID = 0xC8 -- flight controller FC_REQUEST_COMMAND = 0x78 FC_RESPONSE_COMMAND = 0x79

FC_REQ & FC_RESP are different. Did you speak at about this adresses? This addresses needs to be edited for try to fix script???

And 1 more question about settings from pages (like PIDS). From bf i cant find addresses for ret and set values for pid setting. But in kissCF.lua in pages (like PIDS) i see different addresses in start of file. Example:

kissfc-tx-lua-scripts/src/128x64/KISS/pids.lua

read = 0x43,
write = 0x44,

Is all setting write at different addresses or it is way to make payload to sent to FC?

[fedorcomander]

look him up on tbs facebook group. he lives there.
