Betaflight SmartAudio vtxtable troubleshooting (WHY DOESN'T SMARTAUDIO WORK) 

My story is exactly the same:)

Considering FPV is developing very rapidly, a book would be outdated within months of release.

Asu 90% of the fpv quad issues and troubleshooting still remains

Yah plus his book would just be a list of RU-vid links 😂

if not a book, why not a pdf version ehhehe

I believe Joshua owns fpvknowitall.com but also Oscar Liang has a great site for text and screenshot content if you're more into reading but I do prefer the video guides myself.

Can u get out op dip mode, it wont save with me aikon2020f4 rush mini vtx with battery in beta and osd settings save and its gone back in pid again.. ?

How did you connect the vtx to agentX? I Can’t figure it out.

Just means you have an older Rush vTX that supports SA 2.0. The newer ones do 2.1.

Do you get device ready yes in betaflight

Half duplex uses one wire. Both USART and UART devices are capable of half duplex. The difference between USART and UART, is that a USART device is capable of using a second wire for clock sync instead of a using a pre-defined baudrate. UART is purely asynchronous and does not use a wire for clock, requiring that the device be configured to sync to the right baud rate on its own. Granted, a USART in synchronous mode is typically half-duplex, but it definitely needs two wires.

"A cool trick is if you unselect "Use Manufacturer's Table" on each row of the VTX table, it ignores the locking and just sets the channel to whatever is set in the table." - No. When the "FACTORY" switch is on the channel is set by sending a band/channel number to the vtx - only SA supports this. When the "FACTORY" switch is off (equates to "CUSTOM" in the CLI vtxtable) then the actual frequency is sent to the vtx - Tramp *ONLY* works this way. Some SA vtx's will support this (generally real TBS) but many will not and only support setting by band/channel (FACTORY) mode. To complicate things further, even if the vtx supports setting by frequency (Tramp and some SA), then it still may not support every frequency. For example it may not allow frequencies outside the normal bands or even those that don't correspond to normal channels. Setting an unsupported frequency can lead to strange results. For example on Matek Tramp vtx's the vtx will stop transmitting if you select a frequency that's not a "real" channel. The behavior depends on how the manufacturer implemented it and there are no predefined ways of responding.

Thanks gents for clarifying.

UAV Tech I know the Unify EVO is on the more expensive side but it has saved me from the VTX tables entirely. Much nicer controlling all of that witching crossfire. Also easier to show up to a group fly and not have to wait to get into the air.

@@parklander6459 ..ME TOO,haha..All my 10 kwads are Evo vtx,s... throttle down,yaw left..and use the Evo,s OSD to set your power....much less bullshit isn't it?

Thanks. Boss !!! XD
