GEPRC F411 35A AIO softserial (T11 R11 pin)

[Alexx2321979]

411 chip not work normal in softserial!
Sbus work through uart1 and conflicts with another device on uart 1. softserial also conflicts with a device on uart 2. the output is simple 411 full she......
tested on both geprc f411aio and jhemcu f411 noxe v3
It is impossible to install 3 devices (vtx hd, cross, gps) only 2 devices. It's better to buy a board with a 405 chip

EmuFlight is based from ButterFlight/Betaflight 3.5.x . EmuF GPS support is severely lacking and I do not know much about GPS configuration.

GEPRCF411_AIO definition seems to already support softserial:

EmuFlight/src/main/target/GEPRCF411_AIO/target.h

Lines 87 to 105 in 731894a

	#define USE_UART1
	#define UART1_RX_PIN PA10
	#define UART1_TX_PIN PA9
	#define USE_UART2
	#define UART2_RX_PIN PA3
	#define UART2_TX_PIN PA2
	#define USE_SOFTSERIAL1
	#define SOFTSERIAL1_RX_PIN PB10
	#define SOFTSERIAL1_TX_PIN PA0
	#define USE_SOFTSERIAL2
	#define SERIAL_PORT_COUNT 5
	#define DEFAULT_RX_FEATURE FEATURE_RX_SERIAL
	#define SERIALRX_PROVIDER SERIALRX_SBUS
	#define SERIALRX_UART SERIAL_PORT_USART1

I'm wondering if UART1 and SOFTSERIAL1 cannot be used at same time due to identical PINs PA0 & PB10. I do not know enough about it.

Only these Baro/Mag are supported if it's any consolation:

EmuFlight/src/main/target/GEPRCF411_AIO/target.mk

this stock firmware. R11 T11 is softserial? i konect GPS bn180, but not work.

[nerdCopter]

i would agree that 11 is softSerial. In Betaflight if you flashed 4.4 or later, you must enable GPS in cloud-build.

you must enable GPS in cloud-build.

sorry, please give more info for this.
(flashing whis this options)
i have Betaflight 4.4.2 newest, gps enable in konfig - UBLOX potr auto, but not work....

[nerdCopter]

if you have an M10 GPS, betaflight 4.5 has support for M10.
Please go to appropriate Discord server for help and support.

Thank you for the information.
F411 known to be less than ideal, but i did not know these details.

F411 also sometimes needs pid_denom = 2 to process all the filters and features. (#915)
