Which version of the flight controller do you have? There is a known issue with the V2.1 board where timer based DShot does not work, and you must use bitbanged...

Seems to be some issue with DShot after the beacon command, but I'm wondering if it has to do with the 4k loop rate, no gyro DMA, and blackbox logging....

Seems to be an issue with losing DMA on SPI2 (used for blackbox and OSD) when DShot bitbang is disabled. Just a poor choice of motor resource pins complicated by...

Copy and paste this into the CLI tab and see if the gyro calibrates: ``` set motor_pwm_protocol = DSHOT300 set pid_process_denom = 2 save ``` If not, add this and...

Maybe an I2C address conflict between the on-board and external baro? A quick search suggests both use 0x77, and the internal and external I2C connections are both I2C1. Not sure...

> board: manufacturer_id: STMI, board_name: STM32F4DISCOVERY You have the wrong Betaflight target flashed. What FC do you have?

Why are you including the DASHBOARD define? @haslinghuis Should we just remove all `#define DASHBOARD_I2C_INSTANCE` lines from configs since this feature is almost never used?

I'm seeing the same behavior with ESP8266 based receivers, but it works properly on ESP32 based receivers. Here's the signal from a BetaFPV Nano outputting 10kHz PWM on pin 1....

> If a flight controller does not support the Crossfire protocol to communicate with a receiver, but it supports the Spektrum satellite protocol, the ExpressLRS receiver can be connected to...
