Bluetooth - SSC32 communication problem

hello there,

have problem with connection bluetooth BTM-222 SPP UART module to SSC 32.

things presented like following:

preconditions: BT module AT coomands setup done, echo off, baud 115200, flow control none, stop bit 1, parity bit none.

  1. made loop trough SSC32 max232 chip between usb-uart cable and BT-uart module.
    run SSC terminal and com port monitoring. BT module “talking” to cable and vice versa.

  2. SSC32 connected via usb-uart cable = all fine servos moving, can access registers etc.

  3. here we are - SSC connected via BT-uart converter = no servo moving, BUT data led is blinking when i sending something from Lynxterm. no access to registers (SSC32 card not found) no reaction to VER command.

i’m out of ideas, bauds everywhere checked triple times, connection to pc is good, tried to play with timeouts with no success. monitoring says that there are good data is being transmitted to SSC but no any little movement :frowning:

anybody have any idea?

issue resolved ( my BT module dont like max232. was connected directly to Mega chip and all fine).
