Solder points BLE 3.2?

Postby probablylost Sat Jun 11, 2022 8:46 am

Hello.
I have a Mi Pro2 manufactured 02/21 that I want to downgrade with st link. It has a V3.2 BLE I am having trouble finding a picture of solder points? it does not have the three points on the right of the board but has them above the switch, same? And does a resistor need to be removed on this model? thank you!

Me again

So I thought i'd give it a go and tried those points on my BLE (1.5.7) and found then removed the c2 resistor on the back of the board.

When running the blePROrec script it cannot connect to target. So I guess i've got something wrong. STlink is powering the device and drivers installed.
Any help would be appreciated. Thanks

I have been able to downgrade BLE 157 to BLE 090 the BLE_V3.2 board with a ST-Link, removing this capacitor marked in the image.

Нужно ли по процедуре перекрошивки впаять на место этот конденсатор ?

Is it necessary to solder this capacitor into place according to the re - crumbling procedure ?
