Unable to obtain a free TCP channel for dialing with the MODA server.
const MODA_ERRORS_TYPE MODA_ETCPCHANNELSBUSY = -4;
MODA is working with several TCP channels. A thread dial with Moda server by locking a channel during the time required for sending/receiving data. Some commands like Camera images retrieval, 'xxxWaitComplete' sensor functions or Sleep/Wait functions can lock the channel during a long time. If your application is using a lot of threads, you should increase the number of Connection's TCP channels.
