Possible problems
After the receiver is bound to the transmitter, the receiver light keeps
flashing slowly and the receiver cannot connect to the transmitter
normally. The reason is that the packet rate of the transmitter and the
receiver are inconsistent. At this time, we can change the packet rate of
the transmitter or connect Betaflight modifies the packet rate of the SPI
ELRS receiver to solve this problem.
The SPI ELRS receiver uses 250Hz by default, which can be
solved by the following two methods
1: Modify the TX module packet rate:
①Enter the ExpressLRS lua script
②Modify the refresh rate of TX module to 250Hz
2: Modify SPI ELRS receiver packet rate:
You need to enter the Betaflight CLI and use the following command:
set expresslrs_rate_index = [index]
where [index] corresponds to the following:
500Hz = 0
250Hz = 1
150Hz = 2
50Hz = 3
For example, if you want to switch the packet rate to 150Hz, you need to
execute the following command in Betaflight CLI:
set expresslrs_rate_index = 2
save
