Another BAUD rate question

Wireless & IoT

Hi all

i’m quite new for this communication protocol

i’ve made a project that uses serial cable that consist of an ADC (TX out) → MAX232 → Commport

The adc and commport i set to 115200 bps … the result is OK

The 2nd project is i took out max232 and change it to Bluesmirf … it seems the data sometimes error and mostly crash (stopped)

My question is, Let say my ADC (its a PIC16F877) i set to 9600baud , the bluesmirf set to 19.2kbps and Commport set to 115,200 bps .

are these correct way ? i mean its not synchronize , but gives a time & eliminate bottleneck of data processing for each components .

I appreciate any comments (I need some info) … thank you …

The BlueSMiRF connected to the PIC will need to have its serial settings the same as th PIC’s (same baud rate), and if you’re using another BlueSMiRF at the PC end, it’ll need to have the same settings as the comm port. It’s OK if the two radio modules have different settings from each other — the Bluetooth communication isn’t affected by the serial settings. It only needs to match up with whatever device the smirf is wired to.
