stm32f103c8tb + nrf51822 connection and programming

[benjaminpeere]

Hello everyone,

Maybe it is a stupid question but I am completely lost,

I have a stm32f103c8tb that I have to use for programming a nrf51822, the thing is I have absolutely no idea how to connect them, if I need to flash the bootloader of the nrf51822 and if I do, how to do it?

For the moment, the idea would be to just have the blink programm from Arduino examples running and make the Bluetooth module visible when I look for Bluetooth devices with my phone.

Thank you for helping me!

Why do you "have to" use the STM32 to do that?

You would need to use an SWD programmer - such as the JLink

It is a project for a company, and this is what they already bought, the project started last year and I have to take it back with the existing items.

Or maybe you mean that I Don't need to use the STM32 to programm it?

the thing is I found an old topic where they say that i can use the STM32 to program it, so i thought it was the good solution

You certainly don't need to.

The more common approach would be to use a proper programmer.

what do you mean?

because in this video : https://www.youtube.com/watch?v=WmCmqN2i_Xo

the guy uses the same items as I do.

I mean exactly what I said!

I said: "you don't need to use an STM32 to do the programming" - note the emphasis.

Sure, it is possible to do it, but you not need to do it: there are other - and, I suggest, better - ways to do it.

Why not just use a J-Link (in particular, the J-Link on a Nordic board) ?
