Hello , I have been trying to get “TOI Firmware” to work with Catus Micro R2 and seem to have a gap in my knowledge. I have installed Nodemcu and both the recent AI thinker firmware 9.5 and 1.1.1 but, the sketch will not communicate with the esp. I had to change some declaration to const in the “firmware of TOI” for it to compile in 1.6.\* … with 1.1.1 and 9.5 I get the following output from serial Free RAM:956 Setting ESP enable on. Reset pin state is:1 Calling app\_init() Entering main loop() Sent: AT Timeout ERROR DID NOT RECEIVE: OK Find “OK ” len:4 buffer:@0 buflen:0 Timeout ERROR, ESP STUCK: Find “OK ” len:4 buffer:@0 buflen:0 Timeout ERROR, ESP still STUCK: No response from ESP8266 will retry in 60s. with Nodemcu internal firmware installed, it states similar but with “=” near AT error. Do I need to solder the pads on the bottom to correctly flash, maybe I’m flashing the wrong? Any help greatly appreciate to make use of this nice little device! ---

Could you please post your sketch here? ---

Hello, I used the github respotory [https://github.com/dherrendoerfer/TOI\_Firmware/tree/master/Cactus\_Micro/beta/TOI\_firmware\_CM](https://github.com/dherrendoerfer/TOI_Firmware/tree/master/Cactus_Micro/beta/TOI_firmware_CM) Found in the link [http://wiki.aprbrother.com/wiki/Cactus\_Micro\_R2\_Tutorial#For\_espduino\_library\_from\_Tuan\_PM](http://wiki.aprbrother.com/wiki/Cactus_Micro_R2_Tutorial#For_espduino_library_from_Tuan_PM) for 1.6.\* I’ve changed all “prog\_char” to “const char” in all files and it compiles without warnings or error. ---

Please try these steps: 1. Use Nodemcu-flasher upload the firmware [0.9.5.2-9600.bin](http://abcdn1.qiniudn.com/ai-thinker-0.9.5.2-9600.bin?attname=) to esp8266 2. Upload the sketch TOI to Cactus Micro 3. Test again Please let me know if this work ---

Hello aprilpea, This did work and communication did between the esp and micro could connect. However for whatever reason all the webpages except the main index would timeout. I suppose the author would need to update the code for this rev or maybe my settings are still somehow incorrect. ---

Did you test with original TOI example code?
