Advice needed please. I am trying to get a WeMos D1 R2 working with a Modtronix inAir9b. It won't boot with SS GPIO15 connected.
The wiring is as follows
* ESP8266 - SX1276
* GND GND
* VCC VCC
* GPIO15 NSS
* GPIO12 MISO
* GPIO13 MOSI
* GPIO14 SCK
* GPIO5 DIO0
* GPIO4 DIO1
*
* Also on the ESP connect GPIO16-RST for deepSleep wakeup
I'm using the Arduino IDE. If I run the Arduno Blinky code with the SX1276 unplugged everything works fine (LED blinks). That is with no code for the SX1276. If I power up with the SX1276 installed nothing happens. Likewise the the LORA code I'm running. It won't run with the SX1276 installed.
However If I disconnect the SS GPIO15 connection the ESP8266 will start up properly and run the code. Obviously the LORA code won't work with SS disconnected. If I plug SX1276 in after the ESP8266 has booted up the code will run and if SS connected the LORA code will run properly.
If I connect the SS line form the SX1276 to GPIO0 instead of GPIO15 everything works properly, except the LORA function doesn't work, but that could be another problem. It doesn't matter if I'm powering with USB or bench supply.
Any ideas welcome.
thanks
