Micro-controller for Transceiver

Question

I want to interface to a short burst data transceiver so I can format the outgoing raw data within an AT command set, which the transceiver module expects. The source device which sends the raw data (usually in ASCII) plugs directly into the transceiver serial RS232 port. Then the data is passed over the LO satellite network (through the module and RF) back to my SBD server. So I'll need to come up with the right algorithm to push that data out, the incoming payload is OK no need to format.

Was thinking of using a 328 micro-controller with Arduino UNO bootloader. What else is there to consider?

Theres a bunch of Youtube selfhelp stuff out there, but I want to make sure I'm not straying by being specific.

So as I imagine you would need 2 Serial ports or a way to switch between the Hpa and the SBD. You could try using the atmega328 and this software Serial https://www.arduino.cc/en/Tutorial/TwoPortReceive , otherwise if you are familiar might be better using an Arm, the stm32f103 should do the trick STM32F103 - STMicroelectronics . Get yourself a Nucleo Board if you would like to go this way....

If you prefer ARM, stick with the STM32F103 and it should cover all you need (and more!). This is the Dev board I was referring to: NUCLEO-F103RB - STMICROELECTRONICS - NUCLEO BOARD, STM32F103RBT6 MCU | element14 Australia Good luck with your project!

Hi DLaw, So, from where is your data coming from? Remember this chip has a single hardware UART. If you can live with that is very likely you can do that using an ATMega328p. Just make sure you use an external crystal on your circuit as the internal oscillator is not stable enough for UART. Another thing to consider is the package size, remember that 328 has only 2Kb of RAM. You can also find some neat software serial libraries out there so you can debug your code while using the hardware UART for the communication. Btw, what's a SBD Serve? Cheers, Mike M.

Hi trevanian ... sorry, I'm not aware of any. Although the solution sounds simple and probably a interesting project to work with, might be difficult to find any budget consulting to create a customized design. Let me know the HPA and SBD equipment models as well your personal e-mail and I'll see if I get someone to have a look on that for you. Cheers, Mike M.
