ExpressLRS Configurator build error for Radiomaster rel 2.5.2

[worthy spear]

Hi
I want to build firmware for RadioMaster TX12 2400 TX, v.2.5.2
Got error like "'stoull' is not a member of 'std'
uint64_t address = std::stoull(mac, nullptr, 16);"
Full log attached.
I was trying to build on two different Windows 10 laptops with the same result.
Please help to solve.

I'm sorry, but I don't have the information needed to help you with this issue. I recommend that you check out the general troubleshooting guide. Another resource to try is the ExpressLRS Discord.

You can no longer build 2.x due to platformio updates. Follow the flashing guide and flash via USB.

EdgeTX Passthrough doesn't work - error - for that version from ExpressLRS Configurator as well.

[inland skiff]

but are you following the flashing guide?
did you installed the VCP drivers needed by the ETX Passthrough?

[worthy spear]

Yes, I think so

If you mean that https://www.st.com/en/development-tools/stsw-stm32102.html

and you're not trying to flash 2.5.2 via etx passthrough do you?

[worthy spear]

I can see my device at COM11

[inland skiff]

post a screenshot

and try the procedure once again and post the !log file should it fail

[inland skiff]

you cannot, I repeat, CANNOT, build 2.5.2 now because platformIO broke it..

the method will not make any diffeence

and since you're flashing via ETX Passthrough anyway, why not just flash straight to 3.5.6?

[worthy spear]

Ok
I am not sure that the latest 3.5.6 is compatible with BetaFpv Cetus Lite receiver (FlySky), I have tried the latest, but it didn't bind to drone.

So I thought I should try the earlier version.

BetaFpv Cetus Lite receiver (FlySky)
are you for real?

ExpressLRS devices only syncs with other ExpessLRS devices

I believe that one-labeled MPM has another module. If you could suggest which external module I can use than?

[inland skiff]

MPM = No ExpressLRS inside

pretty much any Micro-sized external ExpressLRS tx module will work with the TX12.. as long as the model is configured right.

[worthy spear]

like https://radiomasterrc.com/products/rm-4in1-module ?

[inland skiff]

that's not an ExpressLRS module..

it's a 4-in-1 module, much like what you already have on the TX12 "MPM"

Multi-protocol Module = MPM

i.e. 4-in-1 (4 rf chip in one package covering multiple protocols)

here's a few expressLRS external modules from RadioMaster that will fit the TX12:
RadioMaster Ranger
RadioMaster Ranger Micro
(these are for 2.4GHz receivers)
Radiomaster Bandit
RadioMaster Bandit Micro
(these are for 900MHz receivers)
RadioMaster Nomad (this can be used for both 2.4GHz and 900MHz, and for the dual-band GemX receivers, like the XR4, XR1, etc)

[worthy spear]

Sorry, but if I want to use FlySky, shouldn't I add 4-in-1 to TX12?

[inland skiff]

the MPM module that's already inside the tx12 should work..

but we can't help you with flysky older AFHDS here..

[worthy spear]

Though my TX12 didn't have MPM, I have TX12 EdgeTX-ELRS, that's why I ask

[inland skiff]

then my bad.. you showed an MPM tx12 above in a video..
