# A7ModuleTest
This is a test program for the [Ai-Thinker A7](https://www.smart-prototyping.com/image/data/9_Modules/101756%20Wireless%20A6C/A6_A7_A6C_datasheet-EN.pdf) module connected to an
Arduino Pro Micro or the [Elecrow 32u4 with A7](https://www.elecrow.com/wiki/index.php?title=32u4_with_A7_GPRS/GSM) module.
## Used PINs
The pin layout is taken from the Elecrow 32u4 with A7 module.
- 4 RESET ... with the Arduino Pro Micro this pin must be connected via a N-channel MOSFET (e.g. IRLIZ44N) to the A7 reset pin.
- 5 ENABLE
- 8 PWRKEY
- 10 GPS RX software serial
- 16 GPS TX software serial (not used)
## Serial Connections
- Serial is console
- Serial1 is the hardware serial port to the A7 GSM UART
- SoftwareSerial( 10, 16 ) serial port to A7 GPS UART (RX=10, TX=16)
## Console Commands
### GPS
you can switch on and off the GPS serial port
- gps=on
- gps=off
### GSM / GPRS
- every command starting with *at* is directly send to the GSM UART
- if you like to send characters not starting with *at* start with a *'*-char as first character.
- *ctrlz* is sending a CTRL-Z char to the GSM UART
## Boot Sequence
At the program start RESET, ENABLE and PWRKEY are set to HIGH level. After 3s RESET is set to LOW level.
