I got a strange error after change the variable RAM_CACHE_SIZE (telelogger.ino) to any value different from 1024. I'm using the Freematics firmware v5 with One+.
Thus, the default value of RAM_CACHE_SIZE 1024 is not enough to send all information. After change this value to 2048 a got strange errors in Server ("UDP data checksum mismatch").

Hi all,
I got a strange error after change the variable RAM_CACHE_SIZE (telelogger.ino) to any value different from 1024. I'm using the Freematics firmware v5 with One+.
My OBD polling has 27 PIDs
ID_POLLING_INFO obdData[]= { {PID_SPEED, 1}, {PID_ETHANOL_FUEL, 1}, {PID_RPM, 1}, {PID_THROTTLE, 1}, {PID_ENGINE_LOAD, 1}, {PID_SHORT_TERM_FUEL_TRIM_1, 1}, {PID_LONG_TERM_FUEL_TRIM_1, 1}, {PID_INTAKE_MAP, 1}, {PID_MAF_FLOW, 1}, {PID_FUEL_LEVEL, 1}, {PID_CATALYST_TEMP_B1S1, 1}, {PID_CATALYST_TEMP_B2S1, 1}, {PID_CATALYST_TEMP_B1S2, 1}, {PID_CATALYST_TEMP_B2S2, 1}, {PID_ETHANOL_FUEL, 1}, {PID_CONTROL_MODULE_VOLTAGE, 1}, {PID_RELATIVE_THROTTLE_POS, 1}, {PID_ABSOLUTE_ENGINE_LOAD, 1}, {PID_AIR_FUEL_EQUIV_RATIO, 1}, {PID_AMBIENT_TEMP, 1}, {PID_ABSOLUTE_THROTTLE_POS_B, 1}, {PID_ACC_PEDAL_POS_D, 1}, {PID_ACC_PEDAL_POS_E, 1}, {PID_COMMANDED_THROTTLE_ACTUATOR, 1}, {PID_TIMING_ADVANCE, 1}, {PID_COOLANT_TEMP, 1}, {PID_INTAKE_TEMP, 1}, };
Thus, the default value of RAM_CACHE_SIZE 1024 is not enough to send all information. After change this value to 2048 a got strange errors in Server ("UDP data checksum mismatch").
