Few days ago i bought ESP-8266 “Ai Cloud Inside” module (I was searching for nodeMCU but i couldn’t find it in local shop, matching image below.)
I’ve got two problems for now:
First: I’m unable to find any matching firmware. Every link i’ve managed to find is dead.
Second: I’m unable to find any working flash tool. I found some articles, i even managed to enter flashing mode (or at least i guess so, blue led flashing for few seconds after to power supply) using Arduino UNO board. I tried to use some which are undedicated to this one, but none worked so far (bad packed id or smth like that, also other errors i can’t remember, pins used etc at the end of this post).
So, what am i asking for?
I’d be grateful if anybody could provide me links for working flash tool (i don’t care if it’s a typical windows exe or a linux terminal script) and (yet again) working firmware. Also checking if this connection scheme used for flashing is right. I’m a beginner at using things such as ESP, still learning, so as much info as it’s possible is a serious advantage for me. Hope i explained everything well enough.
Connections i’ve used:
- [ESP – Arduino]
- VCC – 3.3V
- CH_PD – 3.3V
- GND – GND
- URXD – TX
- UTXD – RX
- GPIO0 – GND (Flashing mode (?))
According to pin scheme:
