Good day all,
I am working on project using the UART component for serial communication with the NEOWAY M590E modem. In my project i wait till the ISR receives +PBREADY before it sends any AT command.
The issue am have is upon sending my AT command using PutString, the command is written into my array which i use to receive response from the modem. Based on my perspective the PutString function is using my isr which was connected to Rx_Int of the UART component.
Please how do i fix this bug?
attached is a copy of my project.
Can it be the case that the modem is configured for echoing the received characters?
Check your variable rxd_cnt, it might overflow / underflow.
the echo was actually the fault. thanks alot. is it possible to ready only the message section of a CMGR or CMGL AT command????
I needed to connect the battery to the contact VBTA for SIM900
Otherwise - after the first activation of the transmitter modem stops responding.
Maybe you will be interested in the project for SIM900
M590E has a lot in common with it
