Besoin d'informations pour le kit télémétrie 433Mhz Reference 0795fB05

Bonjour,
j’ai fait l’acquisition de ce système afin de l’utiliser avec un contrôleur de vol autre qu’un Pixwawk.
Pour la communication TTL sur le drone, j’utilise le port mini-usb avec la définition suivante : “gnd - 5v - rx - tx”.
Je ne peux voir les données du contrôleur par un flash de la LED sur le kit, est-ce normal ?

Inversez Rx et Tx : Rx ne se connecte pas sur Rx.
Exemple : Un module transmet via Tx vers un autre module qui reçoit en Rx et inversement. Classique sur ces composants …

TELEMETRY PROBLEM

Yes, since we use your mini-USB port as a connection, there is no Rx,Tx definition on your side and we have already tried both possibilities, no LED flash on the kit.

What else problem could it be?

If not power on : module fried due to reversed ground and 5v

Yes, thanks for your assumption…

For my understanding, The 4 wires of mini-USB is universally defined as: Red for the 5V and black for the gnd, we have to test maximum 2 times to find the RX-TX connection.

Are there any other posibillties or my understanding is not good?

Thanks very much…

yes that’s it. Test your module directly by connecting to computer.
Btw, I don’t understand what you are trying to do … Connect to a jst port on pixhawk not micro usb, it will not work …

Yes I understand, but we have Another flight controller(not pixhawk ), and the data
sended/received is RS232, so, in our case, we have to adapted with an RS232 to TTL kit, and the definition for the TTL is (5V,GND,TX,RX)…

The adaption for mini-USB I think maybe it’s not the perfect but I assume it works… but now it didn’t. What did you mean by it will not work? Do you assume that the mini-USB/TTL on your kit is not working in this way?

Thanks for your reply
